6,600 Questions
Why are the rainforests being destroyed?
They are being destroyed because of business owners and farmers who are cutting down the trees and driving out the wildlife. They want the wood for furniture and so they can build or farm on the land. Also disease and fire play a major role in the killing of trees and animals.
Examples of tropical rainforest plants include orchids, bromeliads, ferns, and epiphytes like air plants. These plants have adapted to the humid and moist conditions of the rainforest to thrive in the diverse ecosystem. They play crucial roles in the rainforest ecosystem by providing shelter, food, and oxygen for a wide variety of wildlife.
What is an example of commensalism in the African savanna?
Commensalism is when two animals work together unwittingly, to help each other survive. An example of this is the relationship between the lion and hyena. The lion makes a kill, eats what she wants, and leaves the rest for the hyena.
Rainforests grow along the Equator in the areas called the tropics, which are hot, sticky and steamy all year round. The biggest forests grow in South and Central America and South-east Asia. There are also smaller forests in China, Australia, India, Madagascar, Papua New Guinea and on some of the islands in the Caribbean Many other countries can claim to have tiny scraps of rainforest.
What is the difference between coniferous forests and deciduous forests?
A coniferous forest has trees like evergreens, they never lose their leaves and they are always green. Like a chirstmas tree before it's cut. A deciduous forest is a forest where the leaves on the trees do turn colors and eventually fall of in the fall and winter. That's just a simple difference though, there are much more complicated differences. Coniferous forests are found in colder climates, in fact the further north you go the less deciduous trees you will find. This also holds true for hot climates . Coniferous trees have evolved needles and thick sap so they lose less moisture to the elements while deciduous trees are usually located in areas of abundant moisture.
Typically - deciduous forests have more clay soil and a higher pH while coniferous forests are more likely sandy and acidic in nature.
Deciduous forests drop their leaves as soon as the growing season ends. A coniferous forest are made up of evergreens that retain their foliage.

Where do butterflies go when it rains?
Butterflies stay under flowers, leaves or other vegetation like a number of other insects do. They will cling to plant stems or the like that are "under" other parts of the plant to get them out of the weather.
about a foot long and half a foot in height, unless there fat!
Pet rabbits range in size from tiny to huge, depending on the breed. Most rabbits fall in the 5 to 10 pound range but dwarf breeds, like the Netherland Dwarf, can be as small as 2 pounds; and giant breeds, like the Flemish Giant, can weigh 20 pounds or more. The current record holder for biggest rabbit is a Continental Giant weighing 50 pounds!
Why do so many animals live in the canopy?
Many animals live in the canopy because it provides abundant food sources, protection from predators on the forest floor, and a diverse range of microhabitats. The canopy also offers access to sunlight for photosynthesis, which supports a high concentration of plant life, making it an attractive habitat for many species.
Caloris basin can be found on this planet?
Caloris basin is found on the planet Mercury. It is one of the largest impact basins in the Solar System, measuring over 1,500 kilometers in diameter. The basin was created by a large asteroid impact early in Mercury's history.
Where is the forest that produces most of Earth's oxygen?
The Amazon rainforest in South America is often referred to as the "lungs of the Earth" due to its high oxygen production. It covers several countries including Brazil, Peru, and Colombia. However, it is important to note that a significant portion of Earth's oxygen also comes from phytoplankton in the oceans.
What is the average rain fall for Poland?
The average annual rainfall in Poland is around 600-700 millimeters. However, rainfall patterns can vary across different regions of the country.
What are some elements of living cells?
There are as many types of living cells as there are organisms on the planet. Almost all living cells, however, feature some common components. Among these essential components are a membrane, membrane proteins, proteins, DNA and transport systems.
What rainforest animal begins with W?
White-faced monkey, White's tree frog, White-bellied Caique and White-headed Parrot. Xo, Smartiiz.
The Epiphytes: Epiphytes include orchids, bromeliads, lichens, mosses and ferns that grow on high branches of trees forming the canopy layer. These are non parasitic plants that derive moisture and nutrients from the air and use their roots merely for support.
The Lianas: These are woody vines that grow up the trunk of other trees and reach up in between the upper canopy layer where there is some gap so that they can get some sunlight. These woody wines also bear fruits and flowers.
The Stranglers: Also known as the killer trees in Spanish, the stranglers begin their life like epiphytes. The seeds are brought to the host tree by the birds. Then, the stranglers spread their roots on the ground where the host tree stands. As they grow, they suffocate and kill the host tree. The result is that an erect strangler is left with a hollow core. Stranglers are the members of the fig family.
Carnivorous Plants: Many of the tropical rainforest plants derive nutrition from other animals. These have a central cavity filled with nectar that attract insects. Once the insects enter the cavity, the downward pointing bristles prevent them from moving out. These plants usually have a lid or flap that close the opening to the cavity. The insect that is trapped inside is then, digested with the help of digestive juices released by the plant. Common carnivorous tropical rainforest plants are the rafflesia, pitcher plant and venus fly trap. Read more on facts about venus fly trap.
What issues face the animals who live in the tropical rainforest?
The natural habitat of many animals in rain forests are being destroyed. This has led to extinction of many of the animals that lived there. Many animals are only found in rain forests. Extinction upsets the food chain, which can lead to the absence of food sources for other animals. This in turn can lead to more extinction of other animals.
Interaction between biotic component?
The biotic components within an ecosystem interact with each other through various relationships such as predation, competition, mutualism, and symbiosis. These interactions play a crucial role in shaping the structure and function of ecosystems. For example, predators help control prey populations, while mutualistic relationships like plant-pollinator interactions contribute to overall ecosystem stability.
What plants can be found around the water ecosystem?
Plants commonly found around water ecosystems include cattails, water lilies, bulrushes, and aquatic grasses. These plants are adapted to thrive in wet conditions and play important roles in the health and balance of the ecosystem.
What green plants produce the most oxygen and why are more of them not planted?
On a per-acre basis, young, fast growing plants produce more oxygen (and consume more carbon dioxide) than older, slow-growing plants.
Why aren't we planting more of them? Because the same people who insist that global warming is a problem, consider agriculture to be one of the biggest environmental polluters out there.
A:Young, fast growing plants produce more oxygen than older, slow-growing plants of the same size, but also produce more carbon dioxide when they die, giving no nett gain in atmospheric oxygen. We do no plant in order to increase atmospheric oxygen levels simply because the present oxygen level is very sufficient and because plants would make no difference anyway.What strange animals live in the rainforest?
Some strange animals that live in the rainforest include the okapi, which looks like a mix between a zebra and giraffe, the aye-aye, a lemur with a unique elongated middle finger for finding insects, and the pink fairy armadillo, a tiny, nearly blind armadillo with a vibrant pink shell.
What was the tallest tree ever recorded?
What was the tallest tree ever recorded?
The tallest trees every claimed by foresters and government surveyors would be the Australian Mountain Ash, or Eucalyptus Regnans, which was once abundant in the state of Victoria, Australia before the 20th century.
The tallest specimens have been recorded by government surveyors between the years of 1850 and 1900. Many extreme measurements from 300 to 500 feet high have been independently attributed for this species. These may have been the tallest trees to ever grow on this planet within human existence. However, scientific verification of these measurements have not been possible in modern times, as the vast majority of the old growth forests have been cleared in the last 120 years. The reports stand alone as the only historical evidence for such height. Several of the well publicized claims from 1860-1885 include:
Mr. G. Klein on Black Spur, near Healesville, estimated a mountain Ash at 480 ft tall.
Mr G.W. Robinson, Surveyor, estimated a tree at the foot of Mount Baw-Baw, at 471 feet in height.
Mr William Ferguson, Surveyor, measuring by tape line a fallen tree near Watts river, 435 feet, from roots to broken top. Reporting to Victorian State Forest Assistant Commissioner, Clement Hodgkinson, 1872.
Mr. David Boyle, Surveyor, measuring a fallen Eucalyptus at Dandenong, 390 ft to broken top, in 1862.
Mr. E. B. Heyne measuring a felled tree at Dandenong, 365 ft to 3ft diam broken top.
Mr. J Rollo of Yarragon estimating a tree at 410 ft.
Mr. Pemberton Walcott estimating a Karri Eucalyptus at 400 feet.
Prof. Wilson and Colonel Ellery measuring a felled tree at Mount Sabine, 380 ft long, 21'8" diam.
The Thorpdale tree was estimated by certified surveyor, George Cornthwaite, at 370 feet, in 1880, and was felled in 1881 and measured along the trunk at 375 feet. His initial measurement with triangulation, was 99% correct.
If even half of the surveyors mentioned above, were correct within 10% of the actual tree's height, then one might conclude there is strong historical evidence for trees in excess of 400 feet once existing on the continent of Australia.
The tallest trees ever recorded on the continent of America, are represented by the coastal Redwood, and the coastal Douglas-Fir of the Northwestern region. Both species are thought to have the genetic and environmental capacity to reach 400 feet.
A claimed height of 424 feet has been attributed to a Redwood felled by the Elk River Mill & Lumber Co. in 1886. The tree measured 21 logs in length.
The "Eureka Tree" a Redwood felled in 1914, was measured at 380 feet.
The tallest confirmed Redwood today, is named Hyperion, and last measured 379.1 feet in 2006, near Orick, Cal. It is a healthy tree, perhaps 500-600 years old, and growing at a steady rate; it may reach 390 feet within this century. Other unexplored trees, may yet be taller.
The Douglas Fir is an enormous conifer which grows to its maximal size along the Oregon, Washington, and British Columbian Coastal waters, and mountain valleys west of the Cascade mountains. The tallest trees today, rarely exceed 300 feet, and the tallest living, in Coos Co. Oregon, is 335 feet tall to lowest portion of trunk, and 11 ft 8 inches in diameter at breast height. It is called the Doerner Fir, and has been calculated at over 500 years of age.
The tallest recorded Douglas Firs on record include:
A Douglas Fir from Lynn Valley, N. Vancouver BC, Felled in 1902 by the "Tremblay Brothers" near Argyle Road and Mountain Highway. Called, "The Tallest Tree of Lynn Valley," measured by the proprietor of land, Alfred John Nye at 410 ft along the trunk, and an additional 5 feet of stump. Bark 13.5" thick, base diameter 14'3."
A Douglas Fir tree felled at Kerrisdale, Vancouver, BC in 1896. It was 13'8" in diameter at the base, excluding bark, and its total length was about 400 feet, according to Julius Fromme, director at Hastings Mill where it was processed.
A Douglas Fir near the town of Mineral, Washington was estimated to have once stood 393 feet high according to the measurements of Richard McCardle, a forester from the University of Washington, in 1924.
In 1900, a 380 foot tall Douglas Fir was measured near the Nisqually River in Washington state, after having been felled by loggers. It was measured with a steel tape by Edward Tyson Allen, a trained forester who was stationed in Portland, Oregon.
How old is the daintree rainforest?
The Daintree Rainforest in Australia is estimated to be around 180 million years old, making it one of the oldest rainforests in the world. It is considered a living museum due to its ancient lineage and unique biodiversity.
Good websites about the rain forest that i can use for a school project?
Some good websites for information about the rainforest for a school project include National Geographic's Rainforest section, Rainforest Alliance, and World Wildlife Fund's rainforest page. These websites provide a wealth of information on the importance of rainforests, conservation efforts, and wildlife within the rainforest ecosystem.
What are the characteristics of the rainforest?
There are two kinds of rainforest. There are temperate rainforests, like the coastal forests in the Pacific Northwest, and there are tropical rainforests, which are in places like South and Central America. Obviously all rainforests have a lot of rain. Also, in all cases that I'm aware of, they have very large trees.
