Question:

What is wrong with looking at an ecosystem through a simple food chain?

Joelle H.
Answer:

Food chains are no longer able to contain the vast amount of inputs different species have on an ecosystem. Food webs that connect multiple different species and organisms through energy flow are much better at being able to show how an ecosystem is functioning. Additionally, when one species in affected in that ecosystem, we are able to see what that may do to others that were connected to it in the food web.
