Question

in a mutualistic relationship between two species, what role does coevolution play?
a both species adapt to the needs of the other so that each species benefits the other
b one species adapts based on the pressure exerted by the other so that only one of the species benefits
c both species adapt to independent environmental pressures that allow them to coexist
d one species fails to adapt to the pressure exerted by the other

Explanation:

In a mutualistic relationship, both species benefit. Coevolution in this context means that both species adapt to the needs of the other to enhance the mutual - benefit. Options B, C, and D do not describe mutualistic coevolution. Option B is a description of a non - mutualistic (e.g., parasitic or commensal) adaptation. Option C describes independent adaptation rather than coevolution in a mutualistic sense. Option D does not represent a mutualistic relationship.

Answer:

A. Both species adapt to the needs of the other so that each species benefits the other
