What is a food web?
Maya AndersonA food web depicts feeding connections (what-eats-what) in an ecological community.
Ecologists broadly lump all life forms into one of two categories called trophic levels: 1) the autotrophs, and 2) the heterotrophs.
Autotrophs are plants and heterotrophs are what eat them and those who eat other.
Also included are minerals and gases and energy from the sun.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
