Question 1 of 5
1. Question
1 pointsCategory: EnvironmentFour of the world’s biodiversity hotspots fall in India. Which of the following factors are considered for a place to become a biodiversity hotspot?
Correct
A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is under threat from humans. To qualify as a biodiversity hotspot, a region must meet two strict criteria: it must contain at least 0.5% or 1,500 species of vascular plants as endemics, and it has to have lost at least 70% of its primary vegetation.
Endemic species are species which are unique to a defined geographic location.

Question 2 of 5
2. Question
1 pointsCategory: EnvironmentConsider the following statements regarding the Salinization.
- Irrigation of land helps in reduction of salinity of soil.
- It occurs on soil due to improper agricultural practices only.
Select the correct statement using the codes given below.
Correct
Salinization is the accumulation of the salts in the soil due to natural reasons or inefficient management practices like over-irrigation of farm land, inefficient water use, poor drainage, allowing water to pond for long periods and allowing seepage from irrigation channels, drains and water storages etc. These salts are detrimental for the crops as water intake is seriously affected.
Irrigation worsens the salinity problem of the soil. In fact, it is the prime cause of it. Statement 1 is thus wrong.
Statement 2 is also wrong as natural reasons are also behind salinization problem.

5. Question
1 pointsCategory: EnvironmentIf a tropical rain forest is removed, it does not regenerate quickly as compared to a tropical deciduous forest. This is because
Correct
Tropical rain forest soil is very poor in nutrient which is required by plants to grow. This is due to acidic nature of soil and incessant rains. Potassium, calcium, magnesium and phosphorous are lost away due to leaching. Thus regeneration is very slow.
