How mining operation cause the destruction of forest?
Mining operations in forest areas have also contributed to the destruction of forests.Mining activities cause soil erosion,while mine wastes and tailings pollute bodies of water.
What food chain or food web are in the amazon rain forest?
In the Amazon rainforest, you can find a complex food web involving various organisms. Some common species in this food web include plants like trees and vines, primary consumers like insects and herbivores, secondary consumers like birds and reptiles, and top predators like big cats and snakes. Each organism plays a vital role in maintaining the balance of the ecosystem.

Have you ever wondered why organisms live where they do and not someplace else? Why do cactuses live in the desert? Why do needle-leaved trees tend to encircle the northern quarter of the northern hemisphere and live in the mountains, but decideous trees live mostly in the eastern half of the United States? Why do waterlillies only seem to live in shallow water? Every organism has certain tolerences. Some need lots of water, some don't need a lot. Some organisms can tolerate extreme cold, others can not. Some organisms need very bright sunlight, others need a dimmer environment. Some animals can live by eating grass, others must live by eating meat. If the living conditions change too much an organism must either leave the area for an area within its tolerances or it will die. Most organisms fall into the second category because they do not have the ability to move dozens or perhaps hundreds of miles to a more tolerable place. If the changes are of a seasonal nature various "over wintering" adaptations (plants go dormant, some animals hibernate, other animals survive only as eggs or immature forms) allow them to persist.
A careful study of any kind of organism's needs would reveal a range of tolerances over which the organism can exist. The sum of these tolerances describes the range of adaptations that an organism can make. This will describe the habitat in which one can expect an organism to live. But what are these fundamental necessities of life? Those things that an organism must be adapted to if they are to survive? They could be anything, however, when it comes to determining the presense or absence of a species, the most important factors are the nonliving or abiotic (without life) factors that affect plant life. Important abiotic factors include water (amount and seasonal distribution), soil (types of minerals and humus content), light (intensity and duration) and termperature extremes (high and low). There is a principle that is called Liebig's Law of The Minimum that states than any factor present in minimal amounts restricts the kinds and number of individuals of a particular species that can live in the area.
These abiotic factors have in effect divided the world into a relatively small number of biomes. A biome is defined as a geographic are which is characterized by particular groups of plants and animals. In North America major terrestrial biomes include tundra, coniferous forest, rainforest, grasslands, decideous forest, and desert. These biomes can be examined at the University of Californiaand at Radford University (Radford, Virginia). Take a virtual field trip there, and pay particular attention to the living conditions, the limiting factors, the types of vegetation (including examples) and the types of animals (including examples).

There are also biotic factors that may be limiting factors. Biotic factors may be density dependent factors or density independent. Density dependent factors have a greater and greater effect as the density of the population increases. These include the effects of competition, predation, parasitism , and crowding. For example, a fungus disease of corn called corn smut can destroy acre after acre of corn costing the farmer his entire crop. However if the fields are smaller and other crops are interspersed the corn smut will have trouble spreading to other corn plants. The population of the fungus will be kept smaller and the population of corn plants will not be reduced as much. Density independent factors, on the other hand, affect a population the same way no mater what the size of the affected population. For example, an ice storm (freezing rain) could damage a population of red maple trees just as much whether there were a lot of these tress or only a few of them.

How might global warming affect tree kangaroos?
Tree kangaroos live in the tropical rainforests of northern Australia and New Guinea.
Two species live in Australia and are restricted largely to high elevation rainforests. This allows them to keep cool and obtain moisture from under the rainforest canopy. A rise in temperatures from global warming will greatly reduce their habitats. Tree kangaroos will be forced up the mountains and restricted to the highest peaks, putting more pressure on their already threatened populations.
They may also be threatened by increased severity of weather events like tropical cyclones. Sudden and dramatic changes to their habitats makes it difficult for animals to forage for food, even for months after a cyclone has passed, because of the loss and destruction of their habitat and resources.
Not so much is known about the habitats of the New Guinea tree kangaroos, so it is unknown if they too are restricted to high elevation rainforests.
What is an example of a food web of the temperate forest?
A food web is too hard to explain just using sentences, so I have provided links that show clear examples (with pictures) of the two main types of temperate forests: Temperate Rainforest Food Web:http://curriculum.calstatela.edu/courses/builders/lessons/less/biomes/rainforest/temp_rain/tempweb.html Temperate Deciduous Food Web:http://curriculum.calstatela.edu/courses/builders/lessons/less/biomes/deciduous/decweb.html
Timber is a product trees. A tree is cut down, sawed into logs of desired lengths, trucked to a sawmill, and cut into timbers of different thicknesses. Ideally, a new tree is planted and the process starts again. Timber is a renewable resource.
What are examples of cooperation and competition between and among species in the mountains?
Some examples of cooperation between species are: animals alerting each other of predators, animals eating insects off of others. Some examples of competition are: fighting for living space and resources, fighting for a mate.
What are some majour abiotic features for the daintree rainforest?
Major abiotic features of the Daintree Rainforest include high precipitation levels, rich and diverse soil composition, high humidity, and a unique topography with steep slopes and valleys. These abiotic factors contribute to the high biodiversity and lush vegetation found in this tropical rainforest.
Logging is important because it actually helps to improve the health of the forest. It removes trees that might otherwise burn and opens areas to the sun, allowing new trees to grow. It is also a way to remove diseased trees so that the diseases don't spread.
How many forest fires are started by camp fires?
thee must have been a lot because a lot of people throw their cigarettes in the forest and a lot of people camp
with a burning fire to keep them warm but the can get out of control
used for making stuff like childrens toys etc
Softwood has a huge range of applications: it is the primary material used for building components, and is also found in furniture and other products such as millwork (mouldings, doors, windows). Softwood is also used in the production of paper, and for various types of board such as MDF (medium-density fiberboard). The finer softwoods have many special uses.
they are used for making window frames,doors,frames,t.v. stands,flooring and beds. people use these all the time actually even to make toys for children.
What would happen if a forest experienced a long term drought?
How an unusually prolonged drought might affect a biological community?Drought conditions increase soil erosion, damage plants, impair water quality, and diminish biological health. Drought also makes areas more prone to invasion of harmful species and insect infestation.
What organisms live in a coniferous forest?
Common organisms found in coniferous forests include animals like black bears, deer, squirrels, and birds such as owls and woodpeckers. Additionally, various undergrowth plants, fungi, and mosses thrive in the cool and moist environment provided by the dense canopy of coniferous trees.
What abiotic factors that best describe a coniferous forest?
Abiotic factors that best describe a coniferous forest include cool temperatures, high precipitation, acidic soils, and long winters with snow cover. These factors influence the type of vegetation and wildlife that can thrive in this ecosystem.
A biotic example is a living organism or a component derived from a living organism within an ecosystem. For instance, plants, animals, fungi, and bacteria are all biotic components of an ecosystem. These organisms interact with each other and with the abiotic components of their environment to sustain life.
What is the geography of the forest?
Deciduous forest have landforms of mountains,valleys,hills, and flat plateus.
The falling oak tree is a physical disturbance to the ecosystem. It results in the death of the ants due to the impact and also creates a canopy that prevents sunlight from reaching the grass below, thus inhibiting its growth.
Where in Canada Is there best forests?
There are not tropical rainforests in the continental United States. However, there are raiforests in Hawaii, as well as Puerto Rico, the U.S. Virgin Islands, and many of the various small island possessions in the Pacific
There are temperate rain forests in Alaska and the Pacific Northwest
The Tongass National Forest
The Chugach National Forest
The Olympic National Forest
There are also pockets of temperate rainforest in the Appalachian Mountains from Georgia to New England.
Finally, there are also some subtropical rainforests in Florida, but only small remnants remain.
What are the characteristics of Alpine Forest?
Dont really know. but if you want to know facts on the desert type in the google bar
what is a desert like?
and go to the first webstite you see :) GOOD LUCK CHUCK
oh and go to google and type in SCARY MAZE GAME!! OMG its so creepy do the maze hehehe
What does Geographic Distribution have to do with evolution?
Geographical Distribution of living species supports evolution because, as species are split up along the planet, they endure changes which better help they adapt to their surroundings. An example of this is with the Finches in Darwin's studies on the Galapagos islands. They all came from the same breed of finch but branched off with different characteristics to survive on the different islands that they were surviving on.
What is the terrain in a deciduous forest like?
i think it is rocky or flat depending on where you are.
What area would be most affected by disruption of the marine ecosystem?
Disruption of the marine ecosystem would most affect coastal communities that rely on fishing as a primary food source and economic activity. This disruption can lead to loss of livelihoods, food insecurity, and economic hardship in these areas. Additionally, marine ecosystems play a crucial role in maintaining global biodiversity and ecosystem balance, so disruption can have far-reaching environmental consequences.
Why is forest vegetation important?
Vegetation provides a certain degree of shelter from weather conditions. Becomes the habitat of many animals such as bears and smaller animals like birds and squirrels. Vegetation also provides the basis of a food pyramid in an ecosystem as the herbivores are the ones to consume the vegetation, then carnivores after, and the decomposers that return the energy back into the ecosystem. Vegetation helps to maintain the balance in soil by using up the nitrogen and the other nutrients. As all creatures need air to survive, the vegetation uses carbon dioxide in the air to use the carbon and instead releases into the air, oxygen which people and many of the earth inhabitants need to survive. the roots of trees and other plants help keep the soil in place so that when it rains, the water won't wash away all the fertile soil in that part of the land. As people being to cut into the forests, more soil erosion occurs and strips away a whole lot of top soil. These are some reasons why vegetation is so important for an ecosystem.
