Front

What is a predator?

Front

What is the significance of a population's geographic range?

Back

A population's geographic range indicates the area over which individuals of a species are distributed, which can affect their survival and reproduction.

Front

What is the difference between biotic and abiotic factors?

Back

Biotic factors are living components of an ecosystem (like plants and animals), while abiotic factors are non-living components (like climate and soil).
