9. What is arboreal habitat?
1. A place where an organism lives is called its habitat.
2. The organisms that live and breed in water are called aquatic organisms and their habitat is called aquatic habitat.
3. The tendency of an organism to develop certain specific features which improve the chances of its survival in the environment in which it lives is known as adaptation.
4. Cacti plants store water in their stems.
6. Plants and animals
8. Plants that live in water are called hydrophytes.
9. The organisms that use trees for their activities are known as arboreal organisms, e.g., all birds, such as the eagle, sparrow, etc., are arboreal and their habitat is known as arboreal habitat.

7. What are the adaptations in the frog?
1• A camel can drink up to 40 litres of water at one time. This water is stored in its body.
• The camel can go without water for several days.
• The camel’s feet have leathery soles for walking on soft, shifting sand. Camels can close
• Their nostrils during a dust storm to protect themselves from sand.
• The hump of a camel stores fat which serves as a food store. This enables the camel to go for
• Days without any food.
• The body of a camel can tolerate high temperatures.
• The long, thick eyelashes of the camel protect their eyes from sand.
2. All non-living things, soil, water bodies, atmosphere and meteorological factors such as sunlight, wind, rainfall and temperature are called abiotic components. Abiotic components are also called non-living components. Living organisms that make up the biotic environment are dependent on each other for their food. All living
organisms such as animals, human beings, plants and microorganisms are called the biotic components. Biotic components are also called living components.
3. • Living things grow on their own up to a certain age. Non-living things do not grow.
• Living things respond to external stimuli. Non-living things do not respond to stimuli.
• Respiration is necessary for living things. Non-living things do not respire.
• Living things produce their own kind.
4. Plants lack organ systems. Animals have special organ systems. Most plants prepare their own food.
Animals cannot prepare their own food. Growth is uniform in plants. Growth is uniform in animals.
Plants are generally autotrophs, i.e., they can prepare their own food. Animals are generally Heterotrophs, i.e., they cannot prepare their own food. They respond very slowly to external stimuli. They respond very quickly to
external stimuli. Plants keep on growing till their death. Animals grow up to a certain age in their life.
5. Xerophytes, such as cacti, usually have special means of storing and conserving water. They often have few or no leaves which reduce transpiration.
6. A habitat provides favourable climatic conditions to survive, breed and flourish.
• It provides sufficient protection to the inhabitants
• It provides sufficient space for movement.
• It provides food materials for survival.
7. Frogs have the following adaptations:
• They have webbed feet that help them to swim in water.
• They have long and strong back legs that help them in hopping on the land for catching their prey.
• Their skin is always moist that helps in breathing through the skin.
