Question

Which of the following is called a dynamic living entity?
A. Village
B. Forests
C. Town
D. Oceans

Answer 1

An ecosystem is a functional unit of nature consisting of biotic and abiotic factors, where the living organism interacts among themselves and also with their physical environment. The relationship between the abiotic community and the non-living environment is always a mutual one, that is, not only does the environment affect the community but the community also modifies the environment.

Complete answer: By harboring a greater variety of plants, the forest provides greater opportunities for food and habitat for the herbivores.
A larger number of herbivores means to increase the 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’ — full of life and vitality.”

** So the correct option is B. Forests**

Additional information: Forest is a system comprising various plants, animals and micro-organisms. In a forest, trees form the uppermost layer, followed by shrubs.
1. The herbs form the lowest layer of vegetation. Different layers of vegetation provide food and shelter for animals, birds, and insects.
2. The various components of the forest are interdependent on one another.
3. The forest keeps on growing and changing and can regenerate.
4. In the forest, there is the interaction between soil, water, air, and living organisms.
5. Forests protect the soil from erosion. Soil helps forests to grow and regenerate.
6. Forests are the lifeline for the forest-dwelling communities.
7. Forests influence climate, water cycle, and air quality.

Note: If forests disappear, the amount of carbon dioxide in the air will increase, resulting in an increase in the earth’s temperature.
1. In the absence of trees and plants, the animals will not get food and shelter.
2. In the absence of trees, the soil will not hold water, which will cause floods.
3. Deforestation will endanger our life and environment.
