- Question 1 of 20
1. Question
Three of the following criteria have contributed to the recognition of Western Ghats, Sri Lanka and Indo Burma regions as hotspots of biodiversity: [2011]
1. Species richness
2. Vegetation density
3. Endemism
4. Ethno-botanical importance
5. Threat perception
6. Adaption of flora and fauna to warm and humid conditions
Which three of the above are correct criteria in this context?CorrectTo qualify as a hotspot, a region must meet two strict criteria: it must contain at least 1,500 species of vascular plants (> 0.5 percent of the world’s total) as endemics, and it has to have lost at least 70 percent of its original habitat. So we choose Species richness as well as Endemism. Along with this Threat perception is necessary to take, because it makes the base of this concept. Adaptation of flora is an arbitrary option, Ethno-botanical importance does nothing with the Biodiversity Hotspot selection criteria, vegetation Density is also discarded.

3. Question
There is a concern over the increase in harmful algal blooms in the seawaters of India. What could be the causative factors for this phenomenon? [2011]
1. Discharge of nutrients from the estuaries.
2. Run-off from the land during the monsoon.
3. Upwelling in the seas.
Select the correct answer from the codes given below:CorrectAlgae multiply rapidly when nutrients are present. So, discharge of nutrients favour algae and subsequently algal bloom growth from estuaries to sea. The run off from the land during the monsoon bring salts which favours the growth of algae. Upwelling of the sea water brings the nutrients to top level leading to rapid algae multiplication.

4. Question
Consider the following: [2011]
1. Photosynthesis
2. Respiration
3. Decay of organic matter
4. Volcanic action
Which of the above add carbon dioxide to the carbon cycle on earth?CorrectPhotosynthesis by plants removes about 120 billion tons of carbon from the air per year, but plant decomposition returns about the same amount. When the organic matter is oxidized through respiration, the reverse of photosynthesis takes place. Respiration releases CO2 into the atmosphere. Respiration and photosynthesis occur at nearly equal rates over one year. Volcanic eruptions and metamorphism release gases into the atmosphere. Volcanic gases are primarily water vapor, carbon dioxide and sulphur dioxide.

5. Question
A sandy and saline area is the natural habitat of an Indian animal species. The animal has no predators in that area but its existence is threatened due to the destruction of its habitat. Which one of the following could be that animal? [2011]
CorrectThe Indian wild ass are also called as ghudkhur in local Gujarati language, is a subspecies of the onager native of South Asia. It is unknown how they disappeared though they have never been hunting target during any emperors in India. The history speaks that their number has been declining after due to diseases such as surra and horse sickness. The process related to salt activities have also been a reason behind it.
