Answers
Answer:
1)Tropical rainforests are warm and humid—the temperature ranges from 21 to 30 degrees Celsius (70 to 85°F). The average annual temperature of tropical rainforests is above 20 °C. These areas often receive lots of sun due to their location around the earth's equator.
2)Most rainforests are structured in four layers: emergent, canopy, understory, and forest floor. Each layer has unique characteristics based on differing levels of water, sunlight, and air circulation.
3)Tropical rainforests occur in areas of tropical rainforest climate in which there is no dry season – all months have an averageprecipitation of at least 60 mm – and may also be referred to as lowland equatorial evergreen rainforest.
4)Temperate grasslands can be found in various regions north and south of the equator including Argentina, Australia, and central North America. Temperatures vary with seasons with tornadoes, blizzards, and fires occurring in many temperate grassland regions.
5)Tropical grasslands have dry and wet seasons that remain warm all the time. Temperate grasslands have cold winters and warm summers with some rain. The grasses die back to their roots annually and the soil and the sod protect the roots and the new buds from the cold of winter or dry conditions.
6)Animals commonly found in tundra include a polar bear, arctic fox, arctic seal, musk ox, harlequin etc. Animals in hot deserts include foxes, jackrabbits, kangaroo rats, pocket mice, badger etc., and in cold deserts include fennec foxes, dung beetles, sidewinder snakes, Mexican coyotes etc.
Agriculture can be called the backbone of India's economic system because two-thirds of the Indian population is engaged in the cultivation of land. Agriculture not only helps to feed the large population, but it also supports the principal manufacturing industries with raw materials.
