Question

select the correct answer.
what term describes a species whose removal would affect many other species, both directly and indirectly?
a. predator species
b. keystone species
c. cascading species
d. phoresy species

Explanation:

A keystone species is crucial in an ecosystem. Its removal has a large - scale impact on other species. A predator species mainly hunts others. Cascading species is not a standard ecological term in this context. Phoresy species have a commensal relationship (one benefits, the other is neither helped nor harmed) and do not have such a wide - ranging impact on removal.

Answer:

B. keystone species
