🔑Concepts
Adaptation is the process by which animals develop special features to survive in their specific environment or habitat.
Terrestrial Animals: These animals live on land. They usually have lungs to breathe and legs to move. Example: Lions, Elephants.
Aquatic Animals: These animals live in water (). They typically have gills for breathing and fins or flippers for swimming.
Amphibians: Animals like frogs and toads that can live both on land and in water (). They breathe through lungs on land and moist skin in water.
Arboreal Animals: Animals that spend most of their time on trees, such as monkeys and squirrels, possessing strong limbs and tails for gripping.
Aerial Animals: Animals that fly in the air, like birds and bats. They have light, hollow bones and wings.
Hibernation and Aestivation: Hibernation is a deep 'winter sleep' to survive cold, while Aestivation is 'summer sleep' to escape heat and dryness.
Feeding Adaptations: Animals are classified as Herbivores (plant-eaters), Carnivores (flesh-eaters), Omnivores (both), and Parasites (living on/in other organisms).
Camouflage: The ability of an animal to blend with its surroundings to hide from predators or catch prey. Example: Chameleons.
📐Formulae
💡Examples
Problem 1:
Why does a Polar Bear have a thick layer of fat called blubber under its skin?
Solution:
The blubber acts as an insulator against extreme cold.
Explanation:
In Arctic regions, temperatures can drop significantly below . The fat layer provides warmth and serves as a food reserve during winter.
Problem 2:
How do fish obtain oxygen for survival in ?
Solution:
Fish use specialized organs called gills.
Explanation:
As water flows over the gills, the dissolved oxygen () is absorbed into the bloodstream, and carbon dioxide () is released.
Problem 3:
Identify the adaptation used by a stick insect to protect itself from predators.
Solution:
Camouflage.
Explanation:
The stick insect mimics the appearance of a twig, making it difficult for predators to spot it against the background of a tree or bush.
