Natural Selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is an adaptation?

Back

An adaptation is a characteristic or trait that helps an organism survive and reproduce in its environment.

Front

What is an example of a structural adaptation?

Back

Gills in fish are a structural adaptation that allows them to breathe underwater.

Front

What is hibernation?

Back

Hibernation is a state of inactivity and metabolic depression in animals, usually to conserve energy during cold months.

Front

What is the role of hollow bones in birds?

Back

Hollow bones make birds lighter, allowing them to fly longer distances.

Front

What is the significance of genetic variation in natural selection?

Back

Genetic variation provides the raw material for natural selection to act upon, leading to evolution.

Front

What is an example of a behavioral adaptation?

Back

Migration is a behavioral adaptation that helps animals find food and suitable climates.

Front

What is extinction?

Back

Extinction is the end of an organism or a group of organisms, often due to environmental changes or loss of habitat.
