Habitat And Adaptation

Animals benefit a lot from their habitats. For example, rabbits live in a forest habitat by building a burrow in the soil; they get food from the plant products; they obtain fresh air they breathe. Habitat provides air, food, water and shelter to an animal.

The place where an organism naturally lives and reproduces is called a habitat.

The soil and climate conditions on land are varied in different parts of the earth. Organisms tend to adjust to the conditions and environment they live in. The unique characteristics of plants and animals that enable them to successfully survive in a particular environment are called as adaptation.

Light :

  • The sunlight is essential for the survival of the biotic components as the sun is the ultimate source of energy for all living things.
  • The sunlight affects growth, flowering, seed germination and in many other ways in plants. Indoor plants put in the shade for a long time grow faster but become delicate and weak.
  • Light also affects animals. Animals living in caves and burrows where sunlight cannot reach have very much reduced eyes e.g., Proteus. Amblyopsis do not have eyes.
  • Nocturnal animals: Some animals like bats, cockroaches and owls are called nocturnal as they are active during the night.

Temperature :

  • Temperature regulates growth, movement, reproduction, morphology and other aspects of life.
  • Animals living in hot areas e.g., snakes, desert rats and lizards are not able to get sufficient water. They have thick skin and do not sweat.
  • Desert animals e.g., camels have long legs. Long legs help them to lift their body above the ground. Thus, they can avoid direct contact with the hot ground.

Water :

All living organisms need water for their survival.

Aquatic plants:

Aquatic plants have the following adaptations:

  • The root system is poorly developed.
    • Air-filled cavities found inside the body make them spongy and buoyant.
    • Leaves in submerged plants are thin and narrow; while in floating plants, they are big and flat with a waxy coating.

Desert plants:

Desert plants carry the following adaptations:

  • Well-developed root systems.
    • Stem is succulent and spongy which helps in storage of water. It is also green and performs photosynthesis.
    • Stomata (sunken) are less in number.
    • Leaves are either very small or converted into spines.

Habitat and Adaptation

The region or place where an organism lives is termed as its habitat. Habitat provides an organism everything it needs to survive like food, shelter, proper weather conditions such as rainfall, heat etc. to breed and flourish.

Fish 

  • Their streamline shape helps to move easily in water
  • Presence of slippery scales

           Gills help in  respiration.

  • Flat fins and tail help in changing direction in the water
  • Tapering ends.
