Question

two closely related shrimp species have habitats and niches that partially overlap. which factor most likely caused the divergence of the shrimp into separate species?
○ reproductive isolation
○ reduction of food supply
○ increase of food supply
○ large initial population size

Explanation:

Speciation (divergence into separate species) occurs when populations can no longer interbreed. Reproductive isolation (e.g., behavioral, temporal, or mechanical barriers) prevents gene flow between groups, leading to divergence. A reduction/increase in food supply or large initial population size do not directly drive speciation; they affect population dynamics but not the reproductive barrier needed for new species formation.

Answer:

A. reproductive isolation
