What part of the ecosystem does each organism fulfill (decomposer, producer, herbivore, carnivore)? kangaroo rat, jackrabbit, cyclops, green algae, shelf fungus

Explanation:

Decomposer- Shelf fungus. This organism act as a decomposer; an organism that breaks down organic material including the remains of dead organisms.

Producer: Green alga; these are mostly autotrophic organisms that manufactures their own food themselves.

Herbivore: Kangaroo rats, jackrabbits: the desert kangaroo rat feeds directly on the producers, also heterotrophs.

Cyclops are omnivores that feeds on both algae and other microscopic debris. They are tiny crustaceans also known as water fleas.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

the answer is c on e2020, bud.
