Keystone Speices Help?
I need some help with this question. I think that the answer is C, but it could be E.
3. Keystone species:
(A) impact the physical structure of a community because they have high biomass.
Both C and E are correct
(C) profoundly impact community composition despite a relatively low biomass or abundance.
(D) prevent the movement of energy from one trophic level to the next.
(B) act primarily as herbivores in a community.
(E) are usually primary producers (plants or other photosynthetic organisms).
