Answer 1

An ecosystem is a community of plants, animals and smaller organisms that live,feed, reproduce and interact in the same area or environment. Some ecosystems are very large. For example, many bird species nest in one place and feed in a completely different area. 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.How does everything fit together in a forest ecosystem versus a meadow ecosystem?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. In other words, if we protect existing natural habitats, we will help to maintain biodiversity (biodiversity is the variety of life in all its forms, levels and combinations). Unfortunately, natural habitats and their ecosystems are more and more endangered because of the damaging environmental effects of growing human populations everywhere.

2: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.

3: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.

4: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

Answer 2

Answer:

The simplest definition of an ecosystem is that it is a community or group of living organisms that live in and interact with each other in a specific environment.

For instance, tropical forests are ecosystems made up of living beings such as trees, plants, animals, insects and micro-organisms that are in constant interaction between themselves and that are affected by other physical (sun, temperature) or chemical (oxygen or nutrients)
