Maharashtra Board SSC (Class 10) Science Part 2 Chapter 4- BYJU’S Important Questions & Answers

1. Reorganize the given food chain. Describe the ecosystem to which it belongs.

Grasshopper – Snake – Paddy field – Eagle – Frog.

Answer: The food chain reorganized gives Paddy field – Grasshopper – Frog – Snake – Eagle.

In this food chain of the ecosystem, grasshopper, is the primary consumer attacking the paddy fields, which are the primary producers. Paddy is cultivated on a large scale in various South Indian states. Similarly, frogs are the secondary consumers, also present in large numbers in the mud of paddy fields, to feed upon grasshoppers. Meanwhile, snakes, the tertiary consumer are also present, and they feed upon their favourite food- the secondary consumers, frogs. Finally, we have Eagles at the top most position in this food chain, and they feed on carnivores like the snake.

2. How can biodiversity be conserved?

Answer: Given here are some points on how biodiversity can be conserved:

1. Protect the rare species of organisms.

2. Set up national parks and sanctuaries.

3. Declare some regions as ‘bioreserves’.

4. Projects for conservation of special species.

5. Conserve all plants and animals.

6. Observe the rules.

7. Maintain record of traditional knowledge

3. What do we learn from the story of Jadav Molai Peyang?

Answer: Jadav Malawi Payeng born into a nomadic tribe of Assam in 1963, is a forest worker since 16 years of age. Once, numerous snakes died in the flood of Brahmaputra River flowing by the village. To prevent this, Molai planted 20 bamboo plantlets. Later, in 1979, the local Social Forestry Department started the social aforestation project on 200 hectares of land. ‘Moloi’ was one among the few who were in charge of that project and he went on to plant the trees even after completion of the project. This resulted in the barren area witnessing the forest cover over the 1360 acres. The jungle in Kokilamukh of Jorhat district of Assam known as the ‘Moloi Jungle’ is the result of his hard work for 30 years. He was awarded with the prestigious ‘Padmashree’ award by the government of India for this unparalleled work. This story tells us that while many people may come together to destroy the forest, a single person, if determined, can establish a new forest!

4. Write a short note about Sacred Grove.

Answer: Sacred Grove is the forest conserved in the name of god and is considered to be sacred by the society. These are not conserved by the government forest department. These areas have special protection, since the sacred grove is conserved in the name of god. There are many such clusters of thick forests present not only in Western Ghats of India but in the entire country. In India, there are over 13000 sacred groves.

5. Give the Classification of Threatened Species.

Answer: Classification of Threatened series is, as mentioned below:

1. Endangered Species: In endangered species, either the number of these organisms is declined or their habitat is shrunk to such an extent that they will be extinct in the near future if conservative measures are not followed. Examples include Lion tailed monkey, lesser florican, etc.

2. Rare Species: These species are depleted, and the number of organisms has declined considerably. Organisms of these species being endemic may be extinct faster. Example: Red Panda. Musk deer and so on.

3. Vulnerable Species: There are very few of these organisms and it continues to decline. A continuous decline in their number is a thing of worry. Examples are Lion, Tiger and so on.

4. Indeterminate Species: These organisms are endangered because of some of their behavioural habits such as shyness. There is not much definite or substantial evidence about the organism. Giant Squirrel is an example.

6. Why is environmental conservation our social responsibility?

Answer: From the time that humans came into being, an interrelationship has been established between us, the human and environment. Humans came into being much after the formation of Earth. However, soon, on the earth, human beings proved their superiority as compared to other animals, claiming their characteristics such as imaginary ability, memory, intelligence and so on as the reason. Humans established domination over nature. Humans also depleted all the natural resources as much as possible. In order to have a satisfactory life, human beings snatched as much as possible from nature, thus causing more problems. Hence, we can see that humans have a crucial role to play in maintaining the balance of the environment. Since we, the humans are responsible for disturbing the environmental balance, then they themselves are in charge of improving the quality of nature.

7. What are some effects of radiation?

Answer: Some effects of radiations are as follows-

  • Cancerous ulceration results from higher radiations of X-rays
  • Destroys the tissues in the body
  • Genetic changes take place
  • Adversely affects the vision

8. What are the sources of water pollution?

Answer: Water pollution results from industrial wastes, domestic waste, sewage, chemicals discharged from industries and pesticides used in agriculture.

9. What are the effects of Soil Pollution?

Answer: Soil pollution causes Soil erosion, retarded growth of plants/ crops, Nutritional deficiency and more.

10. What were the factors affecting the formation of the ecosystem?

Answer: Ecosystem is created by biotic and abiotic factors and their interactions with each other. Each factor plays a very important role in the ecosystem.
