Production of more individuals than environment can lead to:
Correct answer: A. Struggle for existence
- A. Struggle for existence
- B. Survival of fittest
- C. Natural selection
- D. Evolution
Explanation
When there are more individuals in a population than the environment can support, competition for limited resources such as food, water, and space intensifies. This competition is often referred to as the "struggle for existence." Individuals must compete with one another for access to these resources in order to survive and reproduce. This struggle for existence is a fundamental concept in evolutionary theory, proposed by Charles Darwin, as it provides the selective pressure necessary for natural selection to operate.

About Darwinism
Darwinism explains evolution through inherited variation, competition for limited resources, survival and reproduction of better-adapted organisms, and natural selection over generations. It is distinguished from Lamarckism because Darwin's explanation depends on selection acting on existing heritable differences, not the inheritance of acquired characteristics.
