8. In a pond, the primary producer is a green alga, Spirogyra; the primary consumer is the crustacean, Daphnia; the secondary consumer is a small fish, the bluegill; and the tertiary consumer is a larger fish, the smallmouth bass.

- The Spirogyra population will probably die.
- The bluegill population will probably increase.
- The Daphnia population will eat something else.

Constructed Response:
Four friends were arguing about the flow of energy between organisms in a food chain. They wondered what happened to the stored energy in the grass as one organism eats another in a food chain relationship. This is what they said:
Tatyana: “I think most of the plant’s energy ended up in the fox”
Molly: “I think most of the plant’s energy ended up in the snake”
Andy: “I think most of the plant’s energy ended up in the grasshopper.”
Mario: “I think the amount of energy that was in the plant stayed the same when it passed
through the organism in the food chain.”
