Question

use the drop - down menus to identify the role of each organism in the food chain. in alaska, salmon feed on tiny plants called phytoplankton. during late summer, salmon gather in rivers to reproduce. grizzly bears visit these rivers to feed on the large number of salmon. phytoplankton are autotrophs. both the salmon and the grizzly bears are consumers. grizzly bears are drop - down menu with options: primary consumers, secondary consumers, tertiary consumers.

Explanation:

To determine the role of grizzly bears, we analyze the food chain: Phytoplankton (autotrophs/producers) are eaten by salmon (primary consumers, as they eat producers). Grizzly bears eat salmon, so they are secondary consumers (organisms that eat primary consumers). Primary consumers eat producers, tertiary consumers eat secondary consumers, so grizzly bears fit secondary consumers here.

Answer:

secondary consumers
