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 drop - down menu. grizzly bears are drop - down menu (options: producers, consumers, decomposers))

Explanation:

For the first blank (Both the salmon and the grizzly bears are):

Salmon eat phytoplankton (producers), and grizzly bears eat salmon. Organisms that consume other organisms (either producers or other consumers) are consumers. Producers make their own food (like phytoplankton via photosynthesis), and decomposers break down dead matter. So salmon and grizzly bears, as they eat other organisms, are consumers.

Grizzly bears eat salmon (which is a consumer that ate producers). In the food chain, organisms that eat other consumers (or producers) are still consumers. Since grizzly bears consume salmon (a consumer), they are consumers. They aren't producers (don't make their own food) or decomposers (don't break down dead matter).

Answer:

consumers

For the second blank (Grizzly bears are):
