In which of the following regions in India coral reefs are found?
- Rann of Kutch
- Gulf of Mannar
- Sundarbans
- Lakshadweep
Select the correct answer code:
Correct
Solution: d)
Corals are not located in Sunderban region due to the high influx of freshwater. Coral needs sea water of optimum salinity, which is diluted by the influx of fresh water from Ganga and Brahmaputra in Sunderbans.
Incorrect
Solution: d)

Question 4 of 5
4. Question
Consider the following statements about Biodiversity loss.
- Biodiversity loss describes the decline in the number, genetic variability, and variety of species, and the biological communities in a given area.
- A loss in biodiversity can make plants and animals more vulnerable to pests and diseases.
- Biodiversity loss is always anthropogenic.
Which of the above statements is/are correct?
Correct
Solution: c)
Biodiversity loss describes the decline in the number, genetic variability, and variety of species, and the biological communities in a given area. This loss in the variety of life can lead to a breakdown in the functioning of the ecosystem where decline has happened.
An area’s biodiversity increases and decreases with natural cycles. Seasonal changes, such as the onset of spring, create opportunities for feeding and breeding, increasing biodiversity as the populations of many species rise. In contrast, the onset of winter temporarily decreases an area’s biodiversity, as warm-adapted insects die and migrating animals leave. In addition, the seasonal rise and fall of plant and invertebrate populations (such as insects and plankton), which serve as food for other forms of life, also determine an area’s biodiversity.

Question 5 of 5
5. Question
Consider the following statements about Fly Ash.
- Fly ash is the end product of combustion during the process of power generation in the coal based thermal power plants.
- At present less than 50% of the Fly ash is utilised.
- Fly ash can be used in combination with other alkaline materials to transform sewage sludge into organic fertilizer or biofuel.
Which of the above statements is/are correct?
Correct
Solution: b)
Fly ash, the end product of combustion during the process of power generation in the coal based thermal power plants, is a proven resource material for many applications of construction industries and currently is being utilized in manufacturing of Portland Cement, bricks/blocks/tiles manufacturing, road embankment construction and low-lying area development, etc.
At present, 63% of the fly ash is being utilised and target is for 100% utilisation of the fly ash. There is need for education and awareness generation.
Fly ash contains heavy metals from coal, a large amount of PM 2.5 and black carbon (BC).
Fly ash, in view of its alkalinity and water absorption capacity, may be used in combination with other alkaline materials to transform sewage sludge into organic fertilizer or biofuel.
