Malaria, yel­low fever and other tropical diseases are widespread. Question 3 What are polar regions?Describe the climate in the polar regions of the earth? Tusks are actually the incisor teeth of elephant. This adaptation (of white colour) helps the polar bear to catch its prey. 2) The big and bulging bright-red eyes of this frog are an adaptation for protection. The migratory birds usually fly high up in the sky where the wind flow is helpful and low temperature aids in dispersing the heat generated by the constant working of their flight muscles in flapping the wings. The red-eyed frog has a green back and a creamy underside It has big and bulging bright-red eyes. (a) (i) and (ii) (b) (i) and (iii) (c) (i), (iii) and (iv) (d) (ii) and (iv) 8. Question 15 Why does Siberian crane come from Siberia every year for few months? NCERT solution for class 7 science chapter 7 Weather, Climate and Adaptations of Animals to Climate will incorporate necessary insight on the concepts involved in the textbook. The coldest region on earth is the – (a) polar region (b) tropical region (c) temperate region (d) coastal region 9. WHAT IS WEATHER ? If a  predator wakes up the sleeping red-eyed frog during daytime, its big and bright red eyes pop open suddenly. • Smooth bark and smooth or waxy flowers speed the run off of water. This arrangement of toes helps the toucan to get a firm grip on the branches of trees. These forests can be located in Australia, Asia, South America, Africa, Caribbean islands, Central America, and on several of the Pacific, Indian Ocean. The tropical regions get plenty of rainfall. Question 5 State few adaptation in elephant which help in their survival? Tropical region Basic characteristics: • The tropical region lies very close to the equator; between 10°N and 10°S. Tropical rainforests are characterized by wet and humid climatic conditions, along with dense forest cover. Class 7: Science: Adaptations of Animals to climate: Adaptation of Tropical Rainforest Animals The body features and habits that help animals (and plants) to adapt to their particular habitats or surroundings are a result of the process of evolution. Big cats also have sensitive hearing. They have sticky pads on their feet that help them to climb trees. Due to this, reindeers migrate to the warmer regions in the south where they get sufficient food. The large ears also help the elephant to keep cool in the hot and humid climate of the tropical rainforest. The lion-tailed macaques live in the rainforests of WesternGhats in India. The big cats are carnivores which eat only the meat (or flesh) of other animals. • Flowers on the forest floor are designed to lure animal pollinators since there is relatively no wind on the forest floor to aid in pollination. All these countries actually belong to the north polar region (which is also called Arctic region). Many tropical areas have a dry and wet season. When applied to present variability and future forecasts of precipitation data, the tolerance adaptation model found large reductions in fitness predicted for populations in high-latitude northern hemisphere regions, although some tropical regions had comparable reductions in fitness. The tropical rainforest is located near the equator that has a hot and humid climate. Tropical rainforest, luxuriant forest found in wet tropical uplands and lowlands near the Equator. 1) Red-eyed frog has developed sticky pads on its feet which help it to climb easily on the trees on which it lives. Days and nights are almost equal in length throughout the year. People living in Tropical Monsoon Climate have adapted to the changes according to their climatic conditions: 1) They have become more dependent on cultivation and agricultural activities as compared to the people living in dessert or eastern lands. Question 9 How toucan are adapted to survive on trees? It also rains heavily in tropical areas. It is physiogeographically and economically rich in natural resources and biodiversity, including many species of agricultural value. Question 14 Why tropical rainforest support a wide variety of plants and animals? • Only shade tolerant vegetation may grow here. A living organism can survive in a particular habitat only if its body is suited (or adapted) to the climate of that habitat. The tropical region is located very close to the equator in which each organism is suited to live in its particular habitat and each organism is adapted to its particular environment. One of the most fundamental differences between temperate and tropical ecosystems is the ambient temperature during winter, which can even drop below freezing in temperate regions, and populations of tropical butterflies that successfully colonized more temperate climate regions are predicted to have evolved a suite of adaptations to cope with local environmental conditions. • Some plants climb on others to reach the sunlight. It is abundant with many species of wildlife and vegetation. Such adaptations of desert plants are described below. One of the most common migratory bird which comes to India every year for a few months is the Siberian crane.When winter sets in Siberia, and it gets extremely cold, the Siberian crane flies thousands of kilometres and comes to warmer places in India such as Bharatpur in Rajasthan , Sultanpur.The Siberian cranes fly back to Siberia when the winter ends there and climate becomes favourable. The seasonal movement of animals from one region to another in search of warmth and food is called migration. 3) Polar bear has a thick layer of fat under its skin: This layer of fat insulates the body of polar bear against heat loss and keeps it warm in cold climate.
