Question

Match List-I with List-II and choose the correct answer.

List-I		List-II
1	Nitrogen rich fertilizers	p	Ozone depletion
2	Carbon dioxide	q	Eutrophication
3	Carbon monoxide	r	Greenhouse effect
4	CFC’s	s	Air pollutant

• A. 1-p, 2-q, 3-r, 4-s
• B. 1-q, 2-r, 3-s, 4-p
• C. 1-r, 2-s, 3-p, 4-q
• D. 1-s, 2-p, 3-q, 4-r

Hint:

Understanding the environmental impacts of these substances is critical for sustainable living.

Answer 1

The Correct Option is B

Matching the environmental impacts with their corresponding pollutants:

1) Nitrogen rich fertilizers - q) Eutrophication: Excess nitrogen causes algal blooms and oxygen depletion in water bodies.

2) Carbon dioxide - r) Greenhouse effect: CO₂ is the primary gas responsible for global warming.

3) Carbon monoxide - s) Air pollutant: CO is a toxic gas that reduces blood's oxygen-carrying capacity.

4) CFC's - p) Ozone depletion: Chlorofluorocarbons destroy stratospheric ozone molecules.

The correct matching is: (B) 1-q, 2-r, 3-s, 4-p

Other options are incorrect because: - (A) Incorrectly links fertilizers with ozone - (C) Mismatches all relationships - (D) Reverses several cause-effect pairs

Answer 2

- Nitrogen-rich fertilizers contribute to eutrophication in water bodies, leading to excessive algal growth.
- Carbon dioxide is a key contributor to the greenhouse effect, trapping heat in the Earth’s atmosphere.
- Carbon monoxide is an air pollutant that binds to hemoglobin, reducing oxygen transport in the body.
- CFCs (Chlorofluorocarbons) cause ozone depletion by releasing chlorine atoms that degrade ozone molecules in the stratosphere.
