S4L1. Students will describe the roles of organisms and the flow of energy within an ecosystem.

1. Identify the roles of producers, consumers, and decomposers in a community.
   
2. Demonstrate the flow of energy through a food web/food chain beginning with
   sunlight and including producers, consumers, and decomposers.
   
3. Predict how changes in the environment would affect a community (ecosystem) of
   organisms.
   
4. Predicteffectsonapopulationifsomeoftheplantsoranimalsinthecommunityare
   scarce or if there are too many.
