NEET BIOLOGY

Detailed explanation-1: -Interspecific competition is a type of competition in which individuals belonging to different species struggle for the same resources in an ecosystem. Intraspecific competition takes place in a community and not in a population. In this, animals compete for food, water and space.

Detailed explanation-2: -The struggle between organisms to survive in a habitat with limited resources is called competition.

Detailed explanation-3: -Option D is Darwinism. Darwinism is a theory of biological evolution stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual’s ability to struggle, survive, and reproduce. So this option is correct.

Detailed explanation-4: -Darwin saw that overproduction and limited resources create a struggle for existence in which some organisms will succeed and most will not. He also recognized that organisms in populations differ from one another in terms of many traits that tend to be passed on from parent to offspring.

Detailed explanation-5: -In a population, more individuals are born than can survive. The available resources in nature are finite (food, water, space, etc.) and the environment is not able to support unlimited growth of a population. This causes an inevitable struggle for existence among individuals (continual struggle for existence).
