Question

which two of the following arrows show matter moving from a tertiary consumer to a decomposer?
the arrow between the swallowtail caterpillar and the black bearthe arrow between the black racer and the bolete fungusthe arrow between the beaver and the bobcatthe arrow between the pine vole and the gray foxthe arrow between the bobcat and the bolete fungus

Explanation:

A tertiary consumer is an organism that eats secondary consumers. A decomposer breaks down dead organisms. We need to find arrows where a tertiary consumer's matter (when it dies) moves to a decomposer.

• The black racer is a tertiary consumer (eats secondary consumers like small snakes that eat primary consumers). The bolete fungus is a decomposer.
• The bobcat is a tertiary consumer (eats secondary consumers like beavers which are primary consumers). The bolete fungus is a decomposer.

Answer:

the arrow between the black racer and the bolete fungus, the arrow between the bobcat and the bolete fungus
