A _____ is a physical environment where a species lives and becomes adapted.
AnnZ [28]

Answer:

Habitat

Explanation:

All organisms are in constant interaction with their environment. This includes both biotic, living things, or abiotic, non-living things, factors. Where this interaction takes place is what we call an ecosystem.

Within each ecosystem, e.g. aquatic or terrestrial, <u>a population, or group of species, lives in a specific physical environment known as a habitat</u>, where they occupy their own niches or roles/functions.

Here, several populations of different species can coexist, however, they have their own roles or, in other words, they have specific adaptations to this area. Habitats could range from oceans, lakes, and rivers to deserts, forests, and mountains.

Therefore, a <u>habitat</u> is a physical environment where a species lives and becomes adapted.
