What is a generalist species?

Back

A generalist species is an organism that can adapt to a wide range of environments and has a diverse diet, allowing it to thrive in various habitats.

Front

What is a specialist species?

Back

A specialist species is an organism that can only live in a specific habitat, eat a limited range of food, or tolerate a narrow range of environmental conditions.

Front

What is a niche in ecology?
