Biological adaptations include changes in structures, behaviors, or physiology that enhance survival and reproductive success in a particular environment. Matter on the Earth cycles among the living and nonliving components of the biosphere. The complexity and organization of organisms accommodates the need for obtaining, transforming, transporting, releasing, and eliminating the matter and energy used to sustain the organism. Each recombination results in storage, use, and dissipation of energy into the environment as heat. Matter and energy are conserved in each change.
Organisms have behavioral responses to internal changes and to external stimuli.
Broad patterns of behavior exhibited by animals have adapted to ensure reproductive success.
