Class 10 Questions And Answers Help You Prepare For Exams

Q.1 Why are some substances biodegradable and some non-biodegradable?

Answer:

Substances that might be rotten and diminished to easier substances by microorganisms functioning on are known as biodegradable and people substances that can not be acted upon by microorganisms and aren’t diminished into easier substances are units known as non-biodegradable substances. Examples of biodegradables – vegetable wastes, paper, cotton etc. On the opposite hand, materials that can not be rotten by the action of microorganisms/decomposers are non-biodegradable. For example- plastic, glass, polyethene etc.

Q.2 Give any two ways in which biodegradable substances would affect the environment.

Answer:

Two ways within which perishable substances would have an effect on the atmosphere area unit –

  • Biodegradable waste is a substance that can be broken down easily and naturally by natural sources like water, oxygen, sun radiation, or microorganisms.
  • Biodegradable waste produces a foul smell and that’s why they result in pollution.

Q.3 Give any two ways in which non-biodegradable substances would affect the environment.

Answer:

Non, biodegradable substances affect the environment in the following ways:

  • As these substances cannot be decomposed by microorganisms, they pollute the soil and water resources.
  • Such materials will harm and even kill animals, if these animals happen to eat them.

Q.4 What are trophic levels? Give an example of a food chain and state the different trophic levels in it.

Answer:

Trophic levels mean the stages in a food chain. Take the example below:
For example:

  • Grass – Trophic level I
  • Grasshopper – Trophic level II
  • Frog – Trophic level III

Q.5 What is the role of decomposers in the ecosystem?

Answer:

Decomposers consume organisms that have died and their decaying remains. They help keep the environment clean through their work.

Q.6 What is ozone and how does it affect any ecosystem?

Answer:

Ozone represents a type of oxygen which exists as a molecular form. Ozone exists in the atmosphere as a gas which reaches its maximum concentration during daytime. The ozone layer protects the Earth by preventing harmful ultraviolet rays from entering the planet. UV rays have been linked to skin cancer, cataracts, and the extinction of plant and animal life.

Q.7 How can you help in reducing the problems of waste disposal? Give any two methods.

Answer:

The following methods can be taken to alleviate the trash disposal issue:

a. Reduce, reuse, and recycle as much as possible.
b. The implementation of intelligent waste management systems requires the use of distinct waste bins which will handle various waste categories.

Q.8 What will happen if we kill all the organisms in one trophic level?

Answer:

All organisms within a specific trophic level must die to halt all energy transfer processes which lead to the subsequent trophic level.

The population will grow excessively at that specific level. The food chain will experience disruption which will result in an ecological system breakdown.

Q.9 What is biological magnification? Will the levels of this magnification be different at different levels of the ecosystem?

Answer:

Biological magnification describes the process through which living organisms accumulate harmful chemical substances such as pesticides in their bodies through all biological processes of their organic systems.. Yes, levels of biomagnification would increase because the biological process level would increase and would be the very best for the uppermost biological process level. It might have an effect on their organic process like growth, replication, etc.

Q.10 If all the waste we generate is biodegradable, will this have no impact on the environment?

Answer:

If the quantity of perishable waste will increase, then this excess perishable waste will certainly have an impression on the surroundings. The surplus perishable waste is rotten by the action of decomposers then it releases harmful greenhouse gases. These gases can accumulate within the atmosphere, inflicting warming. Perishable waste is recycled simply by the decomposers like bacteria and fungi. It’ll have solely this dangerous impact on our surroundings that several of the gases discharged throughout the decomposition method might end in global warming.
