Adaptation

Front

What is adaptation?

Back

The process by which animals become better suited to their environment through the evolution of characteristics that improve their ability to survive and reproduce.

Front

What are the 3 types of adaptations?

Back

• physiological,​

• anatomical, and ​

• behavioural

Front

What is Physiological Adaptations​

Back

These are internal body processes or functions that increase an animal's chances of survival. For example, the production of venom in snakes helps them incapacitate prey and defend against threats.

Front

What are Anatomical Adaptations

Back

• Structural features of an animal's body—such as the wings of a bat or webbed feet of a duck—enhance their ability to survive in particular environments.​

Front

What are Behavioural Adaptations

Back

Specific actions or patterns of activity, like bird migration or nocturnal living, help animals find food, escape predators, or cope with environmental extremes.

Front

What is Variation?​

Back

Variation refers to the differences between individuals within a species, which can manifest in appearance, behaviour, physiology, and dietary preferences.

Front

What is Heritability of Variation​

Back

Much of the variation between individuals is a result of differences in their genetic material (DNA), and many of these traits are passed from one generation to the next.

Front

What causes variation in animal species?

Back

changes in lifestyle, diet, and environment.

Front

What is natural selection?

Back

is the process whereby organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is Evolution?

Back

is the process by which variation creates a change in characteristics over many generations.
