Where Do We Fit?
The local environment in which an organism lives is its habitat. An organism's niche is its role in the environment which includes what it eats, what eats it, what organisms it competes with, and how the abiotic components interact and influence it. A human being is the only organism that has the ability to alter its habitat, and is found at the top of the food chain.
