The ability of an organism to live successfully in an environment is known as adaptation. Adaptation refers to the ability of an organism to adjust to its environment by changing its physical, behavioral, or physiological characteristics. These changes allow the organism to survive and reproduce in the environment, and to compete successfully for resources. Adaptation is a key concept in evolutionary biology, as it is through adaptation that species can evolve over time to better fit their environment. Resistance refers to the ability of an organism to withstand or fight off a particular stressor, such as a disease or toxin. Competition refers to the interaction between two or more organisms competing for the same resources, such as food or habitat. Succession refers to the process by which an ecosystem changes over time, as different species come and go in response to changes in the environment.
