Front

What is the process by which individuals that are better suited to the environment survive and reproduce?

Back

Natural Selection

Front

How does the overproduction of offspring impact natural selection?

Back

It increases genetic variation within the population but also leads to greater competition for limited resources.

Front

What conditions are needed for natural selection to occur?

Back

A. Variation in traits among individuals, B. Survival of individuals with favorable traits, C. Limited Food Supply.

Front

Define Natural Selection.

Back

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

Front

What is the significance of genetic variation in a population?

Back

Genetic variation increases the chances of survival and adaptation to changing environments.

Front

Explain the term 'Adaptation'.

Back

Adaptation refers to the process by which a species becomes better suited to its environment.

Front

What role does competition play in natural selection?

Back

Competition for limited resources leads to the survival of the fittest, where only the best-adapted individuals survive.

Front

What is the difference between evolution and natural selection?

Back

Evolution is the change in the heritable traits of a population over generations, while natural selection is the mechanism that drives evolution.
