Question

which organism in this food web would you expect to have the greatest amount of biomass if a biomass pyramid was created for this ecosystem?
elephant seal
sea otter
horn shark
kelp crab
sea urchin
kelp

Explanation:

In a biomass pyramid, producers (organisms that make their own food, usually plants or algae) typically have the greatest biomass because they are the base of the food web, and energy transfer between trophic levels is inefficient (only about 10% of energy is passed on). Kelp is a producer in this food web, providing energy to primary consumers like sea urchins and kelp crabs. Higher trophic levels (consumers) depend on lower levels, so producers have more biomass to support the rest of the ecosystem.

Answer:

Kelp
