 A.Answer the following quetions:-

Question-1 Define an Ecosystem.

Solution:An ecosystem is a community of plants, animals and smaller organisms that live,feed, reproduce and interact in the same area or environment. On the other hand, some ecosystems may be physically small, such as you would find in a meadow at he edge of a forest, or in a coral reef in the ocean.

 While some species may be found naturally in both areas, the species that live in the forest ecosystem are usually very different from those that inhabit the meadow, even though the two environments are right next to each other.

 Question-2 What factors are responsible for the distribution of plants and animals in India?

Solution:Distribution of plants and animals on the earth is determined mainly by climate. However the other factors are soil, relief and drainage, though most of them are also interrelated.

 Question-3 What is a bio-reserve? Give two examples.

Solution:A protected area reserved for the conservation of endangered species of flora (plants) and fauna (animals) in their natural habitat. The Sunderbans in the West Bengal and Nanda Devi in Uttaranchal are the two examples.

 Uses of Biosphere Reserve

In a biosphere reserve, endangered species of animals and plants are protected.

This important heritage (of plants and animals) is transmitted to the future generations in all its natural vigour and glory.

The surrounding areas are reserved for research work for the betterment of flora and fauna.

 Question-4 Name two animals having habitat in tropical and montane type of vegetation.

Solution:The common animals found in the tropical forests are elephants and monkeys and the common animals found in the montane forests are Kashmir stag and spotted dear.

 Question-5 Distinguish Between Flora and Fauna.

Solution:Flora

The flora of a country consists of plant kingdom of that country. It covers trees in the forests, other flowering and non-flowering frees grown by man, grassland, scrubs, fens, etc. India possesses about 47,000 different species of plants and 5,000 of them are exclusively found in India.

 Fauna:The fauna of a country consists of birds, fish and animals. It also includes amphibians, reptiles, mammals, small insects and worms. The fauna of India is quite rich and varied. There are about 89,000 species in India.

 Question-6 Distinguish Between Tropical Evergreen and Deciduous Forests

Solution:Tropical Evergreen Forests: Evergreen forests (or Tropical Rain Forests) are found on the rainy parts of the Western Ghats and the island groups of Lakshadweep and the Andaman and Nicobar Islands.

 Ebony, mahogany and rosewood are the most important trees of the Evergreen Forests.Teak is the most dominant species of the deciduous forests. Other trees found here are bamboos, sal, shisham, sandalwood and khair.

 Deciduous Forests:Deciduous forests are found mostly in the eastern parts of the country – northeastern states along the foothills of the Himalayas, Jharkhand, West Orissa and Chhattisgarh and the eastern slopes of the Western Ghats.

 

 Question-7 Name different types of Vegetation found in India and describe the vegetation of high altitudes.

Solution:The following major types of vegetation may be identified in our country:

 

1.     Tropical Rain Forests

2.    Tropical Deciduous Forests

3.    Tropical Thorn Forests and Scrubs

4.    Montane Forests

5.    Mangrove Forests
