Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Carbon monoxide → Greenhouse effect (I)
Carbon monoxide (CO) contributes indirectly to the greenhouse effect by increasing methane levels in the atmosphere and reducing the natural cleansing capacity.
Step 2: Hydrocarbons → Photochemical smog (II)
Hydrocarbons are major precursors in the formation of photochemical smog, especially when reacting with nitrogen oxides in sunlight.
Step 3: Oxides of nitrogen → Acid rain (III)
Nitrogen oxides (NO and NO2) react with water vapor to form nitric acid, contributing to acid rain.
Step 4: Ozone near earth's surface → Impaired plant growth (IV)
Tropospheric ozone is a harmful pollutant and oxidant that inhibits photosynthesis and impairs plant growth.

Top Questions on Ecology
- Which one or more of the following would make a plant community more susceptible to invasion by exotic plants?
- The table below describes the number of tree species in a forest whose seeds are dispersed by large or small animals, and whether they are insect or wind pollinated. In the past, seed dispersers and pollinators were abundant in this forest. Now, there are very few large animal dispersers, but the number of small animal dispersers has not changed. There are also very few insect pollinators in this forest. Which one or more of the following inferences about trees in the forest can be drawn from these changes in seed dispersers and pollinators?
- In a grassland (P), there are 8 plant species with a similar number of individuals of each species. In another grassland (Q), there are 12 species with uneven abundances. Which one of the following statements about the Shannon’s diversity index of P and Q is correct?
- Fungus S infects elm trees and fungus T infects chestnut trees, and both kill their hosts within a year of infection. A forest with equal density of elm and chestnut trees is colonized by both pathogenic fungi. A 100 years later, the elm tree population has declined and the chestnut trees have become extinct. Which one of the following mechanisms would NOT contribute to this outcome?
Figure F shows how predation rate changes with increasing prey density.
Which one of the figures represents the per capita death rate of prey under the conditions of F?
