Study Notes
Adaptations
- Adaptations are changes or modifications in the physical or behavioural characteristics of an organism that help it to better survive and thrive in its environment.
- Organisms adapted to their natural habitat can thrive in their environment, such as obtaining air, food, and water, protecting themselves from predators and reproducing.
Structural Adaptations
- Structural adaptations are physical features that help animals survive in their environment.
-
Examples of Structural Adaptations:
- Hummingbird's long beak to reach deep into flowers to extract nectar.
- Tree lizard's long tail for balancing on branches.
- Giraffe's long neck to reach high leaves and branches in environments where food may be scarce.
- Duck's webbed feet to increase surface area for paddling to hunt or escape from predators.
Behavioural Adaptations
- Behavioural adaptations are changes in the way an animal behaves that help it to survive and thrive.
-
Examples of Behavioural Adaptations:
- Migration: Birds flying thousands of miles to warmer climates during winter to avoid cold weather and access food and shelter.
- Hibernation: Conserving energy during the winter months by sleeping.
- Social behavior: Forming groups for protection against predators.
