Question

which animal has the highest biotic potential?
a bird that only nests in one type of tree and rarely reproduces
a fish species that lays thousands of eggs and lives in many environments
a plant that requires rare soil minerals and grows very slowly
a mammal that is easily wiped out by small environmental changes

Explanation:

Biotic potential refers to an organism's ability to reproduce and survive. A fish laying thousands of eggs (high reproductive rate) and living in many environments (broad ecological tolerance) has higher biotic potential. The bird reproduces rarely, the plant has low growth/reproduction and rare requirements, and the mammal is vulnerable—all have lower biotic potential.

Answer:

a fish species that lays thousands of eggs and lives in many environments
