A
The process of adding earthworms to the waste material to help decomposition.

B
Using ultraviolet radiation to kill ,the harmful microorganisms present in the drinking water.

C
Cutting pupil of the eye with the laser beams to give better sight to the people.

D
Medication used to remove dandruff of the hair.
Solution
- Vermicomposting is a method by which compost or mixed manure of organic origin is prepared by the use of earthworms.
- It is a controlled degradation or decomposition of the organic wastes for the consumption of earthworms which helps in the recycling of food wastes, reduces the waste bulk density and the final product may contain hormone-like substance which accelerates the plant growth.
So, the correct answer is 'The process of adding earthworms to the waste material to help decomposition'
Question 3
1 / -0

Ecological imbalance in the biosphere is created by

A
Cutting of forests

B
Conservation of forest

C
Production of more plastics

D
Both A and C

Solution

Deforestation means the felling and clearing of forest cover or tree plantations in order to accommodate agricultural, industrial or urban use. It involves permanent end of forest cover to make that land available for residential, commercial or industrial purpose. Deforestation can also be seen as removal of forests leading to several imbalances ecologically and environmentally. Synthetic products are materials that are made by chemical processes that are formed artificially by chemical synthesis such as plastic bags, chairs, toys, etc. These synthetic materials can last for years and cannot be decomposed by decomposers. These synthetic products like different plastic products are made up of plastic; this creation of man hinders the flow of materials in the biosphere. Improper disposal is one of the reasons why synthetic products become of the problems and causes of ecological imbalance. It destroys ecosystem that can kill the organism and at the same time it causes various problems in the living world such as pollution.
Therefore, the correct answer is option D.

A
Bury the plastic bags in the soil

B
Use biodegradable plastic bags

C
Throw the plastic bags into the river

D
Burn the plastic bags in a rubbish dump

Solution

The plastics are the non-biodegradable wastes because they are synthetic polymers which cannot be acted upon by the microbes. The plastics should not be dumped in the soil, river or rubbish dump. The biodegradable plastics should be used which will reduce the pollution and the problems created by the use of plastics.
Thus, the correct answer is option B.
Question 8
1 / -0

Choose the incorrect statement about plastics.

A
Plastics are widely used.

B
Plastics are light and attractive.

C
Plastics are biodegradable.

D
All of the above

Solution

Plastics are lightweight, strong, and durable materials. They are cheaper than metals and therefore, are widely used in industries and household articles. They can be moulded into different shapes and sizes and can be of different colours and hence, they look attractive.
Plastics are non-biodegradable as they cannot be decomposed by decomposers (earthworms, microbes, etc.)
So, the correct option is C.
Question 9
1 / -0

Find the odd one out:

A
Plastic

B
Paper

C
Rind or fruit

D
Excreta of animal
Solution
Correct option: A
Explanation:
Waste is often categorised into biodegradable and non-biodegradable.
Biodegradable waste tends to be decomposed by the nature itself such as paper, animal excreta, fruit and vegetable waste, etc.
Non-biodegradable ones cannot be decomposed by nature and they tend to remain in soil or water for a great amount of time. Example-plastic.
Hence, "plastic" is the odd one out.
