Variety of animals and plants living in forests build a rich biodiversity. Different animals and plants play different role in the system of a forest. For example; herbivores are needed to eat green plants and to provide food for the carnivores. Similarly, carnivores are needed to eat the herbivores and check their population. This biodiversity make forests more productive, stable and resilient. If there is no grass, all herbivores would die. If there are no carnivores, all herbivores would eat up all the plants and there is shortage of food. If there are no decomposers, the dead remains of plants and animals would pollute the environment. Due to such biodiversity a balance in nature is maintained.

(i) Oxygen is given out by plant leaves.
(ii) Carbon dioxide is consumed by the plants to prepare their food by the process of photosynthesis.
(iii) Decomposers play an important role in providing nutrients to plants.

Lesser number of trees will be available due to deforestation. In this condition of absence of trees the soil will not hold water leading to floods.

(iv) Kerosene

A Greater variety of plants and animals in the forests helps it to regenerate and grow. Greater variety of plants means more food and habitat for the herbivores. An increase in herbivores means more food for carnivores. Decomposers help to maintain the supply of nutrients to the soil and to the growing plants. This wide variety makes forest a dynamic living entity.

No, they would not have seen the same type of plants and animals. This is so because climatic conditions in the two forests would vary leading to variations in the types of plants and animals

Boar, bison, Jackals, procupine, elephants live in the deeper areas of the forest.

The forests harbouring greater variety of plants,.It provides greater opportunities for food and habitat for the herbivores. Larger number of herbivores means increased availability of food for a variety of carnivores. The wide variety of animals helps the forest to regenerate and grow. Decomposers help in maintaining the supply of nutrients to the growing plants in the forest. Therefore the forest is a dynamic living entity. That means full of life and vitality.

The green plants and trees present in the forest utilize carbon dioxide from the environment during the process of photosynthesis and release oxygen in the atmosphere. This oxygen is inhaled by the animals during respiration. Animals release carbon-dioxide during respiration which is absorbed by plants. In this way the oxygen and carbon dioxide cycle goes on. Since forests contain a large number of plants and trees, they help in maintaining the balance between oxygen and carbon dioxide in the atmosphere.

All the green plants absorb Carbon dioxide for photosynthesis and release oxygen to the atmosphere. Thus they help to maintain the balance in Oxygen and Carboxdioxide level in the air (atmosphere) so he forests are called as green lungs.

(d) Porcupine

We can say that ‘Podu’ is responsible for decline of forests. The tribals left their traditional food, and depended on crops. So the land in forests is changed as agriculture land.

(c) creating flood conditions.

Soil Erosion : Gradual removal of top layers of the earth.

Global warming : Rapid increase in Earth’s average surface temperature.

Correct option is d) Bread

a) Evergreen forests

They definitely oppose and reject the suggestion. 

Eg: 

All their festivals are related to trees. Mamidi panduga, Gongura panduga, Mutyalamma panduga etc. They may cut a branch or some else but not the trees. They don’t cut their home.
