Ans: Forest is a place where grass, small plants and trees grow on their own without being planted.
Ques 4: Why do you feel they are growing on their own?
Ans : In forests, seed dispersal takes place by means of air, water and animals. The conditions required for the germination of seeds are present in the forests. Seed germination takes place in the presence of air, water and warmth of sunlight. During this process, a seed gives rise to a seedling, which further grows into a plant. In this way, plants grow on their own in forests.

Ques 1: Do you remember what the elders of this village used to say?
Ans: The elders of this village used to say “Agar perh hain to hum hain”. According to them, plants and animals can survive without humans, but it is impossible for humans to survive without them.
Question 2: Do you think we could survive if there were no trees and no animals? Discuss this in your class.
No, it is not possible for us to survive without trees and animals.
Trees are very important for us as they provide oxygen for breathing. They also give us fruits, vegetables, wood and various other products.
Similarly, animals provide meat, eggs, dairy products (milk, cheese, etc.), wool, etc. They are also used by humans for various other purposes such as carrying loads, protecting house from thieves, etc.
Thus, we can say that we cannot survive without trees and animals.
