Question

Which of the following are most likely to be keystone species in an ecosystem?

A. small-bodied, primary consumers
B. symbionts
C. large-bodied, higher level consumers.
D. producers

Answer 1

Large-bodied, higher level consumers are most likely to be keystone species in an ecosystem as they exert a significant influence on the population sizes of other species.

Step-by-step explanation:

Keystone species are the species in an ecosystem that have a disproportionate impact on the ecosystem relative to their abundance. They play a crucial role in maintaining the structure and function of the ecosystem. In this case, large-bodied, higher-level consumers (option C) are most likely to be keystone species. These top predators have a significant influence on regulating the population sizes of other species and can have cascading effects on the entire food web.

Answer 2

I think species that are most likely to be in the ecosystem are D. producers
