Lessons > Food Web > For Your Consideration

Ecosystems have an extremely complex web of cause and effect. Changing one connection or altering the population of any species within an ecosystem can have dire, cascading effects on all others within that ecosystem. More information about ecosystems is available in Unit 4, and an exploration of human impacts on ecosystems and biodiversity can be found in Unit 9. Consider the following:

1. How does a natural ecosystem offer suggestions toward a more economical and eco-friendly human model?
2. How do humans affect the greater food web? In this model, how could humans who do not live in the ecosystem still manage to alter the flow of energy within the web?
