Detailed explanation-1: -An adaptation is any heritable trait that helps an organism, such as a plant or animal, survive and reproduce in its environment.

Detailed explanation-2: -The biological fitness of an organism is dependent on its ability to survive and reproduce in a given environment. If different traits or alleles increase the fitness of an organism, those alleles will consequently increase in the gene pool, and that trait will increase in the population.

Detailed explanation-3: -An inherited characteristic that allows an individual organism to survive and reproduce (either sexually or asexually) is called an adaptation.

Detailed explanation-4: -Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

Detailed explanation-5: -Definition: A biological characteristic with a heritable basis that improves reproduction and/or survival and results from evolution by natural selection.
