Let us now learn about some major habitats Major Habitats of the World four major habitats of living beings in different colours. Look at the map of the world given below. It shows the habitats. The four major habitats in the world are polar Refer to the key in the map to identify the different habitats regions, deserts, grasslands, and oceans. These are the natural homes of different plants and animals.

Some regions are very cold and covered with ice, while some arehabitats very hot have different living have very little water. How do plants and animals survive in different living conditions? during the day and Inorder to survive in their habitats, plants and some features.

What happens to plants and animals that fail to adapt? Animals and plants that fail to adapt to the changes in their halbitats may not survive. reducing slowly, and they soon disappear from the earth. Let us understand this better Their numbers keep with an example. Large, lizard-like animals called dinosaurs lived on the earth for millions of years. The last dinosaur died about 65 million years ago. Some scientists believe that the temperature on the earth got too hot for them to survive. However, some other smaller animals continued to live. Let's Think Whydid dinosaurs not survive, while some other animals did? Write down your answer on WS 3.

Hence, they are very cold and SUN Seal remain covered with ice for the major part of the year. Even the Polar region Summers here are very cold. These regions receive litle rainfall throughout the year, and Moss cold winds blow here at high speeds. To survive in the polar habitat, a plant or an animal must adapt to cold and difficult conditions. Plants such as moss, short grasses, and shrubs are found here. Polar bears, seals, and walruses are some of the animals found here. Let us look at some adaptations shown by plants and animals in this habitat.

Let us learn more about Conditions in Deserts Camel An oasis The days are very hot, and the nights are very cold. Cactus There are only a few areas where water is available. An area in a desert where water and plants can be found is called an oasis. We can find some special kinds of plants around an oasis. Desert fox Plants such as cacti, palm trees, and desert lilies survive here. Desert snake Animals such as camels, desert snakes, and foxes are found in deserts. To survive in the desert habitat, a plant or an animal must adapt to the hot and dry climate of this region. Let us look at some adaptations shown by plants and animals in this habitat.
