2.2.5 - Adaptations

Adaptations

Adjustments to an organism's environment to increase its chances of survival.

Behavioral Adaptations

Relate to how an organism acts to increase its likelihood of survival, such as huddling for warmth or migrating.

Structural Adaptations

Physical characteristics of an organism, like color and shape, that enhance survival.

Physiological Adaptations

Traits relating to an organism's internal systems, such as venom production or hibernation.

Phenotype

Characteristics that create genetic diversity, often resulting from mutations.

Genetic Diversity

Variations within species that occur due to inherited traits and mutations.

Success Criteria for Studying Adaptations

Includes comparing structural, physiological, and behavioral adaptations and identifying those in species.

Examples of Structural Adaptations in Plants

Leaf shape, root systems for water uptake, and reproductive structures for pollination.

Examples of Structural Adaptations in Animals

Features like insulation, movement, and predator deterrence that enhance survival.

Importance of Adaptations

Help organisms survive and reproduce in changing environments over time.
