Question

habitat

• is any part of the earth suitable to ______ permanently or temporarily for migratory species
• all organisms require habitat for survival
• influences fitness (or ______)
• for example, females produce more offspring in suitable habitat

Explanation:

For the first blank, a habitat is a place where organisms live, so the word should be "inhabit" (as it means to live in a place). For the second blank, in the context of biology (especially ecology and evolutionary biology), fitness is related to reproductive success (how many offspring an organism produces that survive to reproduce), so the term "reproductive success" fits here as the example given is about females producing more offspring in suitable habitat.

Answer:

First blank: inhabit
Second blank: reproductive success
