Correct Answer: (d) Temperate evergreen forest
Solution:Temperate evergreen forests are found in mid - latitudinal coastal regions. Tropical rainforests are found in Central and South America, western and central Africa, southern India, Southeast Asia, the island of New Guinea, and Australia.

Mediterranean vegetation is mainly found around the Mediterranean sea in Europe, Africa and Asia Monsoon forests are scattered across Southeast Asia's equatorial parts, the Americas, Africa and Australia

13. Where is maximum biodiversity found? [C.P.O. S.I. 5.06.2016 (Shift-I)]

Correct Answer: (a) Tropical rainforest
Solution:The maximum biodiversity is found in tropical rain forests as they are less seasonal, they are neither too hot nor too cold and are more predictable. Therefore, this is the correct option.

These kinds of environments help in promoting niche specialization and also leads to greater species diversity.

14. Where is more than half of the world's biodiversity (diversity of plants and animals) found? [S.S.C. Online Constable GD 1.03.2019 (Shift-III)]

Correct Answer: (b) Tropical rainforest
Solution:More than half of the world’s biodiversity is found in the tropical rainforests, especially in regions like the Amazon Rainforest in South America, the Congo Basin in Africa, and the Southeast Asian rainforests.

Therefore, this is the correct option. These kinds of environments help in promoting niche specialization and also leads to greater species diversity.

15. As one moves from the polar region towards the equator the diversity of plant and animal species [S.S.C. Online Stenographer 14.09.2017 (Shift-I)]

Correct Answer: (a) increases.
Solution:As one moves from the polar region towards the equator the diversity of plant and animal species "increases". The climate near the equator is more suitable in comparison to the poles. The temperatures near the poles are not optimal for growth.

16. Which of the following ecosystems has the highest biomass? [S.S.C. Online C.P.O.S.I. (T-I) 5.07.2017 (Shift-II)]

Correct Answer: (d) Forest Ecosystem
Solution:Biomass is the mass of living biological organisms in a given area or ecosystem at a given time. In an ecosystem, the rate of generation of biomass is called biomass productivity. The Forest Ecosystem has the highest biomass as it includes organisms of all trophic levels compared to other ecosystems.

17. Which of the following is least likely to be an effect of global warming? [S.S.C. Online C.G.L.(T-I) 4.09.2016 (Shift-I)]

Correct Answer: (c) Decreased rate of photosynthesis in vegetation
Solution:Decreased rate of photosynthesis in vegetation is least likely to affect global warming. Carbon dioxide warms the Earth because it is a greenhouse gas in the atmosphere, but it also causes plants to provide less evaporative cooling.

18. Ozone saves the biosphere by absorbing high energy radiations called [S.S.C. Online C.G.L.(T-I) 30.08.2016 (Shift-II)]

Correct Answer: (c) Ultraviolet rays (UV)
Solution:Ozone saves the biosphere by absorbing high-energy radiations called Ultraviolet rays. The Stratosphere zone of the earth's atmosphere contains a layer of ozone (03) which prevents the earth's surface from about 99% of incoming solar UV radiations.

19. The minimum short-term natural hazard is ___ . [S.S.C. Online C.G.L.(T-I) 1.09.2016 (Shift-I)]

Correct Answer: (d) Bolt of lightning
Solution:Volcanic eruptions, earthquakes, flash floods, landslides, severe thunderstorms, lightning, and wildfires are all examples of sudden natural hazards which develop with little warning and strike rapidly. However, a bolt of lightning is the minimum short- term natural hazard of all, which lasts a few seconds.
