Why a person with an allele for a particular trait may not have a phenotype that shows that trait?
An individual with a recessive allele for a trait may not exhibit the phenotype if they also have a dominant allele masking the expression of the recessive allele. This is known as the principle of dominance in genetics. The recessive allele will only be expressed phenotypically if an individual inherits two copies of that recessive allele.
What is the main source of energy that powers most ecosystems on earth?
The sun
Added: This is definitely true. Sunlight affects all surface and shallow water ecosystems.
All though the sun provides us with a primary source of energy for almost all of earth's ecosystems, with proof of greenery from photosynthesis; this is not the case in such areas like the land of the Sahara desert and the Southwest climates of the USA. The lack of abundant water is another factor.
Does taking shorter showers help the environment?
Yes, taking shorter showers helps conserve water, which is good for the environment because it reduces water waste and energy used for heating water. It also helps preserve water resources for future generations.
How could climate change affect the ecosystems of the island nation of Samoa?
Climate change could lead to rising sea levels and increased frequency of extreme weather events in Samoa, which may cause coastal erosion, flooding, and damage to habitats. This could disrupt ecosystems, especially coastal ecosystems like coral reefs and mangroves, which are important for biodiversity and provide protection from storm surges. Changes in temperature and precipitation patterns could also affect the distribution and abundance of plant and animal species on the islands.
Can earthworms be harmless to the ecosystem?
Yes, earthworms are beneficial to the ecosystem as they help to improve soil fertility by breaking down organic matter and improving soil structure. They also play a key role in nutrient cycling and can increase plant diversity in ecosystems.
What are some biotic factors of a sloth?
Some biotic factors of a sloth include the types of trees the sloth feeds on, the presence of predators like jaguars and harpy eagles, and the symbiotic relationships with algae and insects that help camouflage the sloth's fur.
What instrument can be used to measure the length of the giant squid?
A tape measure or sonar technology can be used to measure the length of a giant squid. These tools can provide accurate measurements of the length of the squid's body from tip to tip of its tentacles.
What will happen if water resources are disappeared in 100 words describe it?
if the resouce water will disappeared so what will happen??
Why aren't the climax communities the same everywhere?
Climax communities vary because they are influenced by factors such as climate, soil conditions, topography, and disturbances. Different regions have different environmental conditions that lead to the development of specific climax communities over time.
What are some nonliving things underwater?
Non-living things underwater include rocks, sand, coral reefs, shipwrecks, and human-made structures like submarines or buoys.
What are the most important transformers of energy in ecosystems?
The most important transformers of energy in ecosystems are producers (such as plants) that convert sunlight into chemical energy through photosynthesis, and decomposers (such as bacteria and fungi) that break down organic matter into simpler compounds and release nutrients back into the ecosystem. These transformers play crucial roles in the flow of energy through the food chain.
What are some of the things that make up a person's environment?
Things that make up a person's enviroment are:
shelter
people
air
trees
Are stars and planets biotic or abiotic?
Stars and planets are considered abiotic because they are not living organisms. They are made up of non-living materials such as gases, rocks, and dust. Biotic refers to living organisms like plants, animals, and microorganisms.
What is one characteristic of a healthy ecosystem?
It must have food, water, and room for animals to live in. If the area is too crowded animals may move on to a different ecosystem. Producers in an ecosystem are the living organisms which provide food for other animals. A good example of a producer is a plant. They can make their own food. Consumers are the animals that eat the food from producers or they eat consumers such as deer, rabbit. If you have same amount of producers and consumers you will have a healthy ecosystem.
What is the role of decomposition in cycling matter?
cycling of mattter is the amounts of nutrients available on Earth, it is to be recycled in order to ensure the extistance of biotics. After a plant or an animal dies, it leaves nutrients behind which is mixed with soil and becomes a part of the biosphere. The nutrients in the soil mixed with gases(o2...)is called nitrogen cycle.
What one kind of interaction between living things is based on food?
Plants are dependent on sunlight to make their food.
Animals are dependent on plant or plant products or other animals for food.
Plants are called autotrophs. Animals are called heterotrophs.
What other living and nonliving things did you see in you school garden or the pond?
Some living things that you might see in a school garden or the pond would be is the plants, flowers, and animals. Though they would not be the same. In ponds, you might find cattails, water lilies, fish, frogs, etc. In a school garden you might find vegetables, herbs, earthworms, bees, flowers, etc.
Some non-living things you might see are rocks, water, soil, etc.
How do plants and animals interact with non living things in ecosystem?
Plants and animals interact with non-living things in an ecosystem through processes like photosynthesis, where plants use sunlight, water, and carbon dioxide to produce energy. Animals feed on plants or other animals for energy, which in turn affects nutrient cycling in the ecosystem. Non-living things like water, soil, and sunlight provide essential resources that support life in the ecosystem.
What is it called when water moves between biotic and abiotic factors?
The movement of water between biotic and abiotic factors is called the water cycle. In this cycle, water evaporates from bodies of water and transpires from plants, then condenses into clouds, falls back to the Earth as precipitation, and eventually returns to bodies of water or infiltrates the ground. This constant cycling of water helps sustain life on Earth.
What is a relationship when one organism lives with another and at least one benefits?
Mutually beneficial relationship means that each separate organism benefits from the relationship in one way or another. In general, this concerns no negative side effects in which case it would be a parasitic relationship or whatever else there is. This can be applied to organisms such as trees, insects, animals, fungi, and of course humans. One major mutually beneficial relationship could be a [good] marriage -- I'll let you discover the different forms of benefits associated with that.
To talk about organisms other than humans, there are birds who live off the backs of tortoises who pull old detritus from their skin. This benefits the birds because it feeds them, and it benefits the tortoises because they're better off from it. There are also plenty of bacteria within the human digestive tract. These bacteria exist, obviously, to serve their own lifeforce through the food we eat. However, they help us to digest otherwise unusable portions of our food, and hence, we benefit too.
A dust storm represents a sudden change in Earth's atmosphere. Dust storms are characterized by strong winds that lift up and carry large amounts of dust particles, impacting air quality and visibility. This sudden event can affect ecosystems, climate, and human health.
What is the lowest of living things in every food chain?
if it is in the ocean plankton which i don't believe exists on land but on land its a circle all life eats the plants if they are herbivorous or omnivores which eat meat of any category and plants like humans you can tell by our canniness used to chew meat in all carnivores such as lions dogs bares and alligators who eat all of the category and the animals who die or are eaten goes in the ground to fertilize the plants ether as a "rotting body" or as feces or poop if you don't know what that means and. if you watch the Disney classic lion king you will see.
What kind of organisms can you find in a freshwater ecosystem?
In a freshwater ecosystem, you can find a diverse range of organisms such as fish, amphibians, insects, algae, plants, and bacteria. These organisms play various roles in the ecosystem, contributing to its biodiversity and overall functioning.
Which two biomes have moderate precipitation levels?
The temperate deciduous forest and grassland biomes typically have moderate precipitation levels. These biomes receive enough rainfall to support a variety of plant and animal species, but not as much as rainforests or tropical savannas.
