"Mono Lake Food Webs"

Bellwork:
1) Are “wolves, rabbits, and vegetation (plants)” a population or a community?
2) Give an example of a population.
3) What is a food chain or food web?

Reading: "Who Eats What?: Food Chains and Food Webs" by Patricia Lauber

Mono Lake Food Web Activity
- Students work in groups of 4
- Each group receives a set of cards, each of which has organisms from the Mono Lake ecosystem
- Students use arrows to create a food web that shows who eats what in the Mono Lake ecosystem
- They record a copy of their food web in their workbooks (the top predator in their food web is the coyote...they also include bacteria to act as a decomposer to break down dead things)
