What are the adaptations that help animals to live in their habitats?

Jobisdone [24]

Adaptations are unique characteristics that allow animals to survive in their environment.
There are three types of adaptations: structural, physiological, and behavioral. Structural adaptations are how the animal's body functions or looks on the outside.

What are 3 ways animals can adapt to their environment?

Animals adapt to their environment in a variety of ways; an animal's color, behavior, defense or diet, for example, may serve adaptive functions.

Color and Pattern Adaptations.
Behavioral Adaptations.
Defensive Adaptations.
Dietary Adaptations.

What is an example of an animal adapting to its environment?

Adaptation can protect animals from predators or from harsh weather.
Many birds can hide in the tall grass and weeds and insects can change their colour to blend into the surroundings.
This makes it difficult for predators to seek them out for food.
