LIFE SCIENCE

Detailed explanation-1: -The concept of the struggle for existence (or struggle for life) concerns the competition or battle for resources needed to live. It can refer to human society, or to organisms in nature. The concept is ancient, and the term struggle for existence was in use by the end of the 18th century.

Detailed explanation-2: -Organisms produce more offspring than-given the limited amounts of resources-can ever survive, and organisms therefore compete for survival. Only the successful competitors will reproduce themselves.

Detailed explanation-3: -Environments cannot support unlimited populations. Because resources are limited, more organisms are born than can survive: some individuals will be more successful at finding food, mating or avoiding predators and will have a better chance to thrive, reproduce, and pass on, their DNA.

Detailed explanation-4: -Interspecific competition occurs between members of different species. It may lead to one species going extinct or both becoming more specialized.
