Lesson Notes

What is adaptation?
-- Adaptation is a special characteristic that enables an organism to survive in its environment.

Why is adaptation important?
-- It helps the organism to cope with the physical factors of the environment.
-- It helps the organism to obtain food.
-- It helps the organism to be protected from its enemies.
-- It helps the organism in its efforts to reproduce.

How do animals adapt themselves to the environment?
-- Adaptation can take place structurally or behaviourally.
-- Structural adaptation: The body of the organism is specially suited to the organism's environment.
-- Behavioural adaptation: The organism behaves in certain ways in order to survive in its living conditions.

Areas of adaptation
-- adaptation for survival in extreme temperature conditions
-- adaptation for obtaining light
-- adaptation for movement and breathing in water
-- adpatation for obtaining food
-- adaptation for protection from enemies
-- adaptation for reproduction

Example

Structural Adaptation:
The water hyacinth has air spaces in roots, leaves and stems that helps them to stay afloat so that the leaves can get sunlight for photosynthesis.












Structural Adaptation:
The American Bald Eagle has claws or talons on its feet that enables it to catch its prey firmly. It has hooked beak that enables it to tear the meat off its captured prey.

It has strong flight muscles that enables it to soar in the sky looking for its prey.

Structural Adaptation:
The snow owl has big, sensitive eyes that enable them to see their prey from high up in the sky and swoop down silently to capture their prey.





Behavioural Adaptation:
It is active at night. It has good night vision that enables them to catch their prey at night. The chances of being caught by bigger predators at night is greatly reduced because they may not be able to see the snow owl.
