Forests: Our Lifeline

Trees in forests help in seeping of water inside the cracks of the soil and thus helps in groundwater recharge. This process is known as infiltration and it also helps in preventing floods. Also, the trees present in the forest prevents the rain from directly hitting the ground and bind the soil together which helps in absorption of the rainwater and thus prevent the flood.

Decomposers are the microorganisms which breakdown the dead plants and animals into simpler substances. The various examples of microorganisms are bacteria, fungi, mushrooms etc.

In the forest, the decomposers help in conversion of dead remains of plants and animals into essential nutrients and these nutrients are provided to trees for their growth.

The role of forest in maintaining the balance between oxygen and carbon dioxide in the atmosphere is as follows:

Plants inhale carbon dioxide gas and exhale oxygen gas using the process of photosynthesis. This helps in creating a balance between oxygen and carbon dioxide in the atmosphere.

The diagram is given below:

There is no waste in a forest because all the waste is being decomposed by the decomposers and it gets absorbed by plants as nutrients.

Five products which we get from forests are as follows:

1. Wood

2. Medicines

3. Spices

4. Fodder for animals

5. Honey from honey-bees.

a. Pollination

Pollination is a process of transfer of pollen grains from anther to stigma of a flower. This process involves role of insect, butterflies, honey bees and birds.

b. water,air

A Forest is a purifier of water and air because it helps in bringing rain and helps in maintaining ground water and provides fresh water. Moreover, forests are responsible for maintaining a balance between oxygen and carbon dioxide gas in the atmosphere and provide fresh air.

c. ground

Giant trees form the top layer in the forest followed by shrubs and tall grasses. Herbs form the ground layer in the forest.

d. soil.

The decaying leaves and animal droppings in a forest enrich the soil because they are highly nutritious when they get converted to humus by decomposers and hence provides enrichment in nutrients to the soil.

we should worry about the conditions and issues related to forests far from us because:

1. Forest provides clean air, clean water.

2. They help in maintaining a balance between oxygen and carbon-dioxide in the atmosphere.

3. Forests gives us various products such as wood, paper, honey etc.

4. Forests helps in preventing floods.

5. They are responsible for bringing rain.

There is a need for a variety of animals and plants in a forest due to the following reason:

For the survival of animals and plants and maintenance of the food chain.

Since insects eat grass and frog eats insects. These food chains are linked to each other. If one of the animal or plant dies, the other will be starved and thus the whole food chain gets disturbed.

The diagram after the labeling is as follows:

The correct answer is: option iv.

Gum, Plywood and Sealing Wax are obtained from forests but kerosene is not obtained from forest.

The correct answer is: option ii.

In a forest, plants and animals are dependent on each other such as in food chain, both plants and animals make up a food chain.

The correct answer is: option iii.

Microorganisms decomposes dead plants and animals to produce humus which is highly rich in nutrients
