(27) Ans: Respiration is the chemical process in which food taken by an organism combines with oxygen to release energy.
- All the living things undergo respiration to obtain energy from food.
(28) Ans: The changes in surroundings to which living things respond are called stimuli. For example, birds fly when they hear a loud sound.
If we touch the leaves of a Mimosa plant with our figures, then its leaves fold up and droop.
(29) Ans: If we move from a dark place into bright sunshine suddenly, then our eyes shut themselves automatically for a momemt.
- In this case, bright light is stimulus and we respond by shutting the eyes momentarily.
(30) Ans: Oxygen is the waste product of plants.
- At night time the plants get rid of waste carbon dioxide through the stomata in leaves. The waste product oxygen is also removed from plants through the stomata in their leaves.

Long Answer Type Questions
(31) Ans: Habitat: The place where a plant or animal lives is called its habitat.
* Some of the examples of habitats are: Deserts, Mountain regions, Forests, Tree, Pond etc.
* Biotic components: Plants, Animals and Micro-organisms.
* Abiotic components: Soil, Rocks, Air etc.
(32) Ans: The presence of specific body features which enable a plant or an animal to live in a particular habitat is called adaption.
* the plants like cactus and animals like camels have developed special body features for surviving in hot and dry areas of desert. This known as adaption to desert environment.
(33) Ans: The plants in desert habitat are well adapted to cope with the shortage of water and high temperature by storing water and reducing the loss of water.
(34) Ans: The desert animals such as desert rats and desert snakes survive by living in burrows during the hit daytime. The desert rats and snakes dig deep burrows in the sand and stay in them during daytime when it is very hot. The burrows stay cool during the day and hence protect these animals from the sun’s heat as well as loss of water from their body.
(35) (a) Ans: (i) The camel has long legs which help to keep its body away from the hot sand in the desert.
(ii) A camel can drink large amount of water and stored on it the body.
(iii) A camel’s hump has fat stored in it. In case of emergency, a camel can break down stored fat to obtain water.
(b) Ans: (i) The cactus plant have modified their leaves in the form of thin spines to reduce the loss of water through transpiration.
(ii) The photosynthesis in cactus plants is carried out by the green stem.
(iii) The cactus plants store water in their stems. The stem of cactus plant is covered with thick waxy layer which prevents the loss of water from it through evaporation.
(c) Ans: (i) The streamlined body shape helps the fish to move through the water easily.
(ii) The fish has special organs called gills which help it to absorb oxygen dissolved in water for breathing.
(iii) The fish has slippery scales over its body which protect the body from water also help in easy movement through water.
