Question

two species of garter snake in the genus thamnophis are found in the same geographic region. these species are not likely to meet and attempt to reproduce because one mainly lives in the water, while the other species spends most of its time on land. this is known as: behavioral isolation habitat isolation zygote mortality temporal isolation

Explanation:

Habitat isolation is a prezygotic reproductive barrier where species occupy different habitats within the same geographic area, preventing them from encountering each other to reproduce. The scenario describes two snake species separated by water vs. land habitats, which matches this definition. Behavioral isolation involves mating behaviors, zygote mortality affects fertilized eggs, and temporal isolation involves different breeding times, none of which apply here.

Answer:

B. Habitat isolation
