Ans. The tributaries of the River Ganga are the Ghaghra, the Son, the
Chambal, the Gandak, the Kosi.
Ans. Bromeliads are special plants that store water in their leaves. Animals like frogs use these pockets of water for laying their eggs.
Ans. The forests are so thick that the dense “roof” created by leaves and branches does not allow the sunlight to reach the ground.
Ans. They mainly grow tapioca, pineapple and sweet potato. Cash crops like coffee, maize and cocoa are also grown.
Ans. In the rainforests of the Amazon we are likely to find birds such as toucans, humming birds and bird of paradise.
Ans. The cities of Allahabad, Kanpur, Varanasi, Lucknow, Patna and Kolkata are located along the River Ganga.
Ans. Animals like monkeys, sloth, ant-eating tapirs, crocodiles, snakes, pythons, anaconda, boa and flesh eating piranha fish are found here.
Ans. The plains of the Ganga and the Brahmaputra, the mountains and the foothills of the Himalayas and the Sundarbans delta are the main features of this basin.
Ans. The main crop is paddy. Wheat, maize, sorghum, gram and millets are the other crops that are grown. Cash crops like sugarcane and jute are also grown.
Ans. Since cultivation of paddy requires sufficient water, it is grown in the areas where the amount of rainfall is high. Ganga-Brahmaputra basin is good for cultivation of paddy as it receives good amount of rainfall.
Ans. In the fresh waters of River Ganga and River Brahmaputra, a variety of dolphin locally called Susu (also called blind dolphin) is found. The presence of Susu is an indication of the health of the river. The untreated industrial and urban wastes with high amount of chemicals are killing this species.
Ans. The developmental activities are leading to the gradual destruction of the biologically diverse rainforests. It is estimated that a large area of the rainforest has been disappearing annually in the Amazon basin. As a result of this destruction, the topsoil is washed away as the rains fall and the lush forest turns into a barren landscape.
Ans. As it rains heavily in this region, thick forests grow. The forests are in fact so thick that the dense “roof” created by leaves and branches does not allow the sunlight to reach the ground. The ground remains dark and damp. Only shade tolerant vegetation may grow here. Orchids, bromeliads grow as plant parasites.
Ans. People grow most of their food in small areas after clearing some trees in the forest. While men hunt and fish along the rivers, women take care of the crops. They mainly grow tapioca, pineapple and sweet potato. As hunting and fishing are uncertain it is the women who keep their families alive by feeding them the vegetables they grow. They practice “slash and burn agriculture”.
