Explain how animals dwelling in the forest help it grow and regenerate. Ans. Animals help in growing and regenerating forests in many ways. Animals work as the cleaning agents in the forest. Microorganisms work on dead bodies of plants and animals and degenerate them. An’imals also help in pollination which helps in growing a number of plants. Herbivores helps the carnivores to grow as they serve as food for them. Thus flora and fauna mutually grow in the forest. Q.2. Explain how forests prevent floods. Ans. Forests can absorb a lot of water. The roots of the trees absorb the water and prevent it from flowing away. Roots of trees also help in percolation of water into the soil. This helps in preventing floods. Q.3. What are decomposers? Name any two of them. What do they do in the forest? Ans. Decomposers are the organisms which feed on the dead bodies of plants and animals. They clean the forests decaying dead bodies and replenishing the nutrients back to the forest soil, e.g.„ beetles and grubs. Q.4. Explain the role of forest in maintaining the balance between oxygen and carbon dioxide in the atmosphere. Ans. Plants release oxygen in the atmosphere during the process of photosynthesis. This oxygen is inhaled by the animals for respiration. During respirat...

The animals in forests are of various types. These could be herbivores, carnivores, micro-organisms, etc. These play an important role in maintaining the food chains. (i) Micro-organisms convert the dead plants and animals to humus. This humus helps in returning the nutrients back to the soil. These are absorbed by plants. (ii) The animals also help in dispersing the seeds of certain plants. (iii) The decaying animal dung provides nutrients to various types of seedlings to grow. All these activities of animals dwelling in the forest help it to grow and regenerate. animals dwelling in the forests help the forest to grow and regenerate. As the animals dwell within the plants the seeds get stuck to the body of animals and after travelling to different places they fall at any time and the forests provides all the important things that a plant needs and helps to grow and regenerate.

Various types of animals (herbivores, carnivores, omnivores) live in forests and contribute to food chain. Following activities show how animals help forest grow and regenerate. 1. Animals help in dispersal of seeds from one part of the forest to other part. 2. Animal’s excreta and their dead bodies when decomposed into soil act as manure for the plants. 3. Microorganisms convert dead plants and leaves into humus which is rich in nutrients. Humus in soil provide necessary minerals for plant growth.

Class 7 Science Forests: Our Lifeline Questions and Answers Exercise Questions Question 1: Explain how animals dwelling in the forest help it grow and regenerate. Answer: Animals dwelling in the forest help it grow and regenerate in the following ways • Animals help in dispersing plant seeds. • Decaying animal dung provides nutrients for plants to grow • Microorganisms convert the dead plants and animals to humus Question 2: Explain how forests prevent floods. Answer: Forest acts as a natural absorber of water. It allows rain water to seep through. In the absence of trees, the rain water would hit the ground directly resulting in flood. However, because of the presence of trees, rain water does not hit the ground directly. It rather hits the ground slowly. Hence, before flooding, all the rain water seeps through ground. In this way, forests prevent floods. Question 3: What are decomposers? Name any two of them. What do they do in the forest? Answer 3: Decomposers are the organisms which feed on the dead bodies of plants and animals. Examples: Fungi and Bacteria. They clean the forests decayin...

Exercises 1. Explain how animals dwelling in the forest help it grow and regenerate. Answer. Various types of animals (herbivores, carnivores, omnivores) live in forests and contribute to food chain. Following activities show how animals help forest grow and regenerate. (i) Herbivores animals clear the land by eating grass for the new growth of vegetation. (ii) Animals also help in the seed dispersal and pollination. (iii) Dead and decaying bodies of animals convert to humus after decomposition which increase the fertility of the soil of the forest. (iv) Dungs of animals provide nutrient to various types of seedling to grow. 2. Explain how forests prevent floods. Answer. Forest acts as a natural absorber of rainwater and allows it to seep. It helps in controlling the flow of water and slows it down which helps in preventing flood. 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 rain water and thus prevent flood. 3. What are decomposers? Name any two of them. What do they do in the forest? Answer. Decomposers are the micro-organisms that convert the dead plants and animals to humus. Bacteria and fungi are the two types of decomposers. They help in the process of recycling of nutrients by decomposing various dead organisms such as plants and animals to form humus. 4.

The animals in forests include herbivores, carnivores, fungi, bacteria, etc. These play an important role in maintaining the food chains. 1. Micro-organisms convert the dead plants and animals to humus. This humus helps in returning the nutrients back to the soil. These are absorbed by plants. 2. Animals which are dwelling in the forest can move or disappear the seeds of various plans and therefore the animal dung acts as a manure can help in growing these seeds to plant. 3. The decaying animal dung provides nutrients to various types of seedlings to grow.
