The Yellowstone area contains organisms representing all trophic levels, including plants, algae, moss, fungi, blue jays, fish, and grizzly bears. Which sequence best represents the transfer of energy through Yellowstone trophic levels?

C. algae to fish to grizzly bear to fungi

Explanation:

A.Fungi to moss to algae to fish

B. blue Jay to moss to fungi to plant

C. algae to fish to grizzly bear to fungi

D. plant to blue jay to algae to grizzly bear

The trophic level of an organism in a food web represents the position such organism occupy in the food web.

Within the food web, energy is transferred from producers to consumers and finally to decomposers.

Option A is incorrect because fungi (a decomposer) cannot start a food web. Option B is incorrect because plant is a producer and as such, cannot end a food web. Option D is incorrect because algae (a producer) cannot be at the middle.

The correct option is C. Algae is a producer, fish is a primary consumer and feeds on algae, grizzly bear is a secondary consumer and feeds on fishes while fungi is a decomposer and decomposes the grizzly bear when it dies.

b. lithosphere, asthenosphere, mesosphere   is the answer most likely
