• The National Biodiversity Authority is an Autonomous and Statutory Body of the Ministry of Environment, Forest and Climate Change, Government of India. Hence, statement 2 is correct.
• It performs facilitative, regulatory and advisory function for the Government of India on issue of Conservation, sustainable use of biological resource and fair equitable sharing of benefits of use.
• The Biological Diversity Act (2002) mandates the implementation of the provisions of the Act through decentralized system with the NBA focusing on advice the Central Government on matters relating to the conservation of biodiversity
1. sustainable use of its components and equitable sharing of benefits arising out of the utilization of biological resources
2. advice the State Government in the selection of areas of biodiversity importance to be notified under Sub-Section (1) of Section 37 as heritage sites and measures for the management of such heritage sites. Hence, statement 3 is correct.

Question 7 of 10
7. Question

With reference to the organizations of ecology, consider the following statements:
1. The population is the total number of different species living in a specific geographical area at a given time.
2. A rapidly growing population will usually contain a large proportion of individuals in the reproductive age group.
Which of the statements given above is/are correct?
Correct
Correct Answer: B
Explanation
• Statement 1 is incorrect. Statement 2 is correct.
• ‘Population’ is defined as a group of freely interbreeding individuals of the same species present in a specific geographical area at a given time. Hence, statement 1 is incorrect.
• Biotic community refers to populations of various kinds of organisms living together and sharing the same habitat. An ecosystem houses several biotic communities which interact with each other. For example, one can observe populations of different kinds of birds, insects and many other animals on a tree, living in the same environment, mutually sustaining and interdependent. This assembly of different organisms constitutes a biotic community. Depending on the mode of nutrition, members of a biotic community are categorised into autotrophs, heterotrophs and saprotrophs.
• Statement 2 is correct. A rapidly growing population will usually contain a large proportion of individuals in the reproductive age group; a stationary population (where there is no increase or decrease in population) contains an even distribution of all age groups, and a declining population contains a large proportion of old or individuals of post-reproductive age.

With reference to the Bee keeping, consider the following statements:
1. Though Input cost and infrastructure cost is low, it is time consuming.
2. It can increase the yields of certain crops.
3. It does not compete for resources with any other agricultural enterprise.
Which of the statements given above is/are correct?
Correct
Correct Answer: D
Explanation
Statements 2 and 3 are correct. Statement 1 is incorrect. Bee keeping requires less time, moneyand infrastructure investments, hence statements 1 is INCORRECT. Beekeeping has positive ecological consequences. Bees play an important role in the pollination of many flowering plants, thus increasing the yield of certain crops such as sunflower and various fruits, hence statement 2 is CORRECT. The Honey bee does not compete for resources with any other agricultural enterprise, hence statement 3 is CORRECT.

With reference to the IUCN Red List of Threatened Species, consider the following statements:
1. It is updated once in every five years.
2. The species listed as ‘Least Concern’ don’t play an important role in terms of global biodiversity.
3. The IUCN Red List website does not include Not Evaluated species.
Which of the above statements given above is/are correct?
Correct
Correct Answer: C
Explanation
Statement 3 is correct. Statements 1 and 2 are in correct.
• The Red List is updated a few times per year. Hence, statement 1 is incorrect.
• Although Least Concern species have a lower risk of extinction, they are still important in terms of global biodiversity. Some Least Concern species are undergoing slow declines. It is important to monitor these species and to develop appropriate conservation actions to prevent them from becoming threatened in the future. The inclusion of Least Concern species on the Red List allows us to track the changing status of biodiversity. Hence, statement 2 is incorrect.
• The inclusion of Least Concern species on the Red List allows us to track the changing status of biodiversity.
• The IUCN Red List website does not include Not Evaluated species. If the species is not on the Red List website, but appears in the search field under the title “CATALOGUE OF LIFE”, this usually means that the species has not yet been assessed for The IUCN Red List and is therefore considered Not Evaluated. Hence, statement 3 is correct.
More about IUCN Red List:
• The IUCN Red List is an authoritative indicator of the health of the world’s biodiversity. The
IUCN Red List is:
1. a powerful tool to inform and catalyse action for biodiversity conservation and policy change, critical to protecting the natural resources we need to survive.
2. provides information about range, population size, habitat and ecology, use and/or trade, threats,
3. provides information about conservation actions that will help inform necessary conservation decisions.

10. Question
2 points
Consider the following statements regarding Global-Warming potential (GWP):
1. It is a relative measure of how much heat a greenhouse gas traps in the atmosphere.
2. It is expressed as a factor of carbon dioxide.
3. A high GWP correlates with low infrared absorption and a long atmospheric lifetime.
Which of the statements given above is/are correct?
Correct
Correct Answer: C
Explanation
Statements 1 and 2 are CORRECT. Statement 3 is incorrect. Global warming potential (GWP) is a measure of how much heat a greenhouse gas traps in the atmosphere up to a specific time horizon, relative to carbon dioxide.
a. Carbon dioxide (CO2)-1
b. Methane (CH4)-56
c. Nitrous Oxide(N2O)-280
d. Sulphur hexafluoride (SF6)-16300
Factors that influence GWP
1. The absorption of infrared radiation by a given species.
2. The spectral location of its absorbing wavelengths.
3. The atmospheric lifetime of the species.
Thus, a high GWP correlates with a large infrared absorption and a long atmospheric lifetime. Hence statement 3 is INCORRECT.
