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?
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

c. Algae to fish to grizzly bear to fungi

Explanation:

Algae are the producers in Yellowstone trophic levels which can be eaten by fish which is a primary consumer. The grizzly bear which is a secondary consumer or carnivores feed on these fish and when the grizzly bear die, fungi which is a decomposer feeds on the grizzly bear and release nitrogenous substances which can be used by the algae for its growth and development. Only 10% of energy is transferred from on trophic level to another whereas the remaining 90% are released in the form of heat energy.
