"Making Food Webs"

Bellwork:
1) An organism that makes its own food is ________________________.
2) Does a primary consumer eat plants or animals?
3) What happens when one member of a food web is removed?

- Review food webs: energy flows from one organism to the next as they eat each other. Arrows show this in drawn food webs.
- Students all complete food webs today using sets of cards. Some work in groups of 2-4, and some work by themselves.
- Using arrows, students create 1-3 food webs that include 1 producer, 1 decomposer, and 4 consumers. The organisms they use are the same organisms they will have to choose from when they complete their CCA next week.
- Students record their food webs in their workbooks
