Question 1 of 5
1. Question
Consider the following statements with reference to Food chains.
- The grazing food chain is found only in terrestrial ecosystem.
- The grazing and detritus food chains are not interlinked.
- The initial energy source for detritus food chain is dead organic matter.
Which of the above statements is/are incorrect?
Correct
Solution: c)
- A sequence of organisms that feed on one another, forma food chain. In nature, two main types of food chains have been found: Grazing food chain and Detritus food chain.
- The grazing food chain starts with producers or autotrophs as base, which is consumed by heterotrophs. It is found in both Terrestrial and aquatic ecosystems.
- The Detritus food chain starts from dead organic ‘matter of decaying animals and plant bodies to the microorganisms and then to detritus feeding organism called detrivores or decomposer and to other predators.
- The two food chains are linked as the initial energy source for detritus food chain is the waste materials and dead organic matter from the grazing food chain.

Question 2 of 5
2. Question
Which of the following is/are the characteristics that the pollutant should possess in order for bio magnification to occur?
- A pollutant should be biologically active.
- A pollutant should be long lived.
- A pollutant should be soluble in fats.
Select the correct answer code:
Correct
Solution: d)
- Bio magnification stands for Biological Magnification, which means the increase of contaminated substances or toxic chemicals that take place in the food chains. These substances often arise from intoxicated or contaminated environments.
- The contaminants include heavy metals namely mercury, arsenic, pesticides such as DDT, and polychlorinated biphenyls (PCBs) compounds which are then taken up by organisms because of the food they consume or the intoxication of their environment.
- Pollutant needs to satisfy characteristics like long life, biologically active, soluble in fat etc. to make bio magnification possible

Question 3 of 5
3. Question
Which of the following adds/add nitrogen to the soil?
- Burning of coal by man
- Death of vegetation
- Excretion of urea by animals
Select the correct answer code.
Correct
Solution: c)
Burning of coal by man is the main source of atmospheric carbon dioxide. It has nothing to do with adding nitrogen to the soil.
Nitrogenous waste products of living organisms such as urea and dead remain of organisms are converted back into inorganic ammonia by the bacteria.
Incorrect

Question 4 of 5
4. Question
Consider the following statements regarding Intergovernmental Panel on Climate Change (IPCC)
- It conducts its own research for assessing climate change.
- It is a joint initiative of World Meteorological Organization (WMO) and United Nations Development Programme (UNDP).
Which of the above statements is/are correct?
Correct
Solution: d)
Created in 1988 by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP), the objective of the IPCC is to provide governments at all levels with scientific information that they can use to develop climate policies. IPCC reports are also a key input into international climate change negotiations.
The IPCC is an organization of governments that are members of the United Nations or WMO. The IPCC currently has 195 members. Thousands of people from all over the world contribute to the work of the IPCC. The IPCC does not conduct its own research

- Ministry of Environment, Forest and Climate Change is the nodal agency for the implementation of the act.
- It recognizes rights of the tribal on the forests if they have resided for at least three generations or 75 years before the cut-off date of December 13, 2005.
- National parks and wildlife sanctuaries are excluded for the recognition of rights under the act.
Which of the above statements is/are correct?
Correct
Solution: b)
Ministry of tribal affairs is the nodal agency for the implementation of the act. National parks and wildlife sanctuaries are included for the recognition of rights under the act.
According to FRA, “forest land” means land of any description falling within any forest area and includes unclassified forests, undermarcated forests, existing or deemed forests, protected forests, reserved forests, Sanctuaries and National Parks;
