Adaptation to Environment Adaptation Is a hereditary characteristics within some organisms in a population. Is a term used to describe the ways in which organisms change over time in response to changing demands of their environment. This characteristics improves an organisms chances to survive and reproduce. If it does, then more organisms with that adaptation are left behind in the coming generation. Organisms that are adapted to their environment are able to: 1. Secure food, water, and nutrients. 2. Obtain air, warmth, and spaces. 3. Cope with physical conditions such as temperature, light, and heat. 4. Defend themselves from their natural enemies, 5. Reproduce and rear offspring. 6. Respond to changes around them. Types of Adaptation 1. Structural 2. Functional (Physiological) 3. Behavioral Structural Adaptation Structural Adaptation are special body parts of an organism that help it to survive in its natural habitat. Skin color Shape Body covering Examples of Structural Adaptations Camouflage An appearance that makes something look like its surrounding; could be its shape or color. Example: chameleon, stick bug Examples of Structural Adaptations Physiological Adaptations Physiological Adaptations are systems presents in an organism that allow it to perform certain biochemical reactions Making venom Secreting slime Phototropism Examples of Physiological Adaptations Behavioral Adaptations Behavioral Adaptations are special ways a particular organism behaves to survive in its natural habitat. 1. Mimicry 2. Hibernation 3. Mating 4. Parenting practices 5. Nest-building 6. Migration Mimicry similarity of one species to another that protects one or both. Hibernation is a state of inactivity and metabolic depression in endotherms. Mating is most often used to describe the pairing of opposite-sex or hermaphrodite organisms, usually for the purposes of reproduction. Parenting practices are specific behaviors, while parenting styles represent broader patterns of parenting practices. Nest building is often driven by a biological urge in pregnant animals to protect one's offspring known as the nesting instinct. Migration the physical movement by animals from one area to another.
