Namaste Dear Shishyans

We are sure you all are familiar with the proverb ‘Absence makes the heart grow fonder’.

Well, this is exactly the case with us ...our inability to be together in school has indeed made us fonder of each of you and made us realize, once more,

how important you are to all of us . You enrich our lives in so many ways and we learn from you just as you learn from us.

We hope you and every member of your family is fine. Take care of yourself

and find time to connect with your family members. Make yourself useful at home by doing small chores, be it laying the table, folding your clothes,

watering the plants, etc.

In order to ensure that you are fruitfully occupied at home we have decided to send you worksheets every week. Do them carefully in any old notebook

or sheets of papers that are available at home. The answers will be sent to you the following week along with a new worksheet.

So get started and let's hope the good times resume soon.

Remember, however grim the situation may seem, the world will bloom once again and so will every bud in Shishukunj !

Revision Notes on “Conservation of Plants and Animals”

Biosphere: Part of the Earth that supports life is called the biosphere. It is here that all living organisms exist.

Biodiversity: Variety of organisms that exist on the Earth, their interrelationships, and their relationship with their environment is called the Biological Diversity and the Biodiversity.

Wildlife Sanctuary: This is a protected area where animals can live in their natural habitat without any disturbance.

National Park: This area is reserved for wildlife allowing them to freely use the available habitats and natural resources.

Biosphere Reserve: Biosphere reserves are larger areas of land which aim to conserve the wildlife as well as the traditional life of the tribal living in the area (allowing them to use the plant and animal resources to some extent).

Deforestation and Its Causes

Deforestation means clearing of forests for different purposes, such as timber and other uses of land.

Major reasons for deforestation are:

Clearing woods to procure land for cultivation and grow more food for the ever-increasing population

Using wood as fuel, to make furniture, and for industrial purposes (e.g., wood pulp is used to make paper)

Using the land for building houses and factories

Forest fires and severe droughts also lead to deforestation.

Species: A group of living organisms that can interbreed with each other are called a Species. It means that only members of one species can reproduce offspring that are fertile and can give birth to future generations. Members of a species look like each other and share many characteristics.
