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: -Fitness describes how well an organism can survive and reproduce in its environment. Individuals with adaptations that are well-suited to their environment can survive and reproduce and are said to have high fitness.

Detailed explanation-3: -Biological fitness, also called Darwinian fitness, means the ability to survive to reproductive age, find a mate, and produce offspring.

Detailed explanation-4: -Fitness describes an organism’s ability to survive and reproduce in a particular environment. Organisms with a high level of fitness for a particular environment have traits that are suitable to the environment in which they live, allowing them to thrive and reproduce.

Detailed explanation-5: -In the crudest terms, fitness involves the ability of organisms-or, more rarely, populations or species-to survive and reproduce in the environment in which they find themselves 6–9. The consequence of this survival and reproduction is that organisms contribute genes to the next generation.
