Study Notes

Definitions

Adaptations: Traits enhancing survival and reproduction of organisms; e.g., penguin feathers provide warmth in cold climates.
Ecosystem: An interactive community of living and non-living components, such as a classroom comprising people and furniture.
Habitat: The specific environment in which a species resides; e.g., camels inhabit deserts.
Camouflage: An adaptation that enables animals to conceal themselves in their environment to evade predators or ambush prey.
Predator: An organism that actively hunts other animals for food; examples include lions and bears.
Prey: An organism that is pursued and consumed by predators.

Penguin Adaptation

Habitat: Penguins are native to Antarctica, thriving in polar climates.
Body Adaptation: Penguins possess dense feathers and a substantial layer of fat, crucial for thermal insulation against the cold.
Feet Adaptation: Penguins have featherless feet, which are kept warm through a countercurrent heat exchange system; cold blood from the feet is warmed by the warmer blood returning from the body, ensuring heat is retained.
