What is desertification

What is human impact
An organism that obtains energy by feeding on other organisms
What is a consumer
A diagram that shows the amount of energy that moves from one feeding level to another in a food web.
What is an energy pyramid
The producer level of the pyramid
Where is the most energy available
nitrogen moves from the air into the soil, into living things, and back into the air or soil
