Question 1 of 5
1. Question
Consider the following statements.
- The amount of nutrients, such as carbon, nitrogen, phosphorus and calcium present in the soil varies in different kinds of ecosystems and also on a seasonal basis.
- Biogeochemical cycles are always gaseous in nature.
- Environmental Factors like soil, moisture, pH and temperature regulate the rate of release of nutrients into the atmosphere.
Which of the above statements is/are correct?
Correct
Solution: b)
The amount of nutrients, such as carbon, nitrogen, phosphorus, calcium, etc., present in the soil at any given time, is referred to as the standing state. It varies in different kinds of ecosystems and also on a seasonal basis.
The movement of nutrient elements through the various components of an ecosystem is called nutrient cycling. Another name of nutrient cycling is biogeochemical cycles (bio: living organism, geo: rocks, air, water). Nutrient cycles are of two types: (a) gaseous and (b) sedimentary.
Environmental factors, e.g., soil, moisture, pH, temperature, etc., regulate the rate of release of nutrients into the atmosphere.

Question 2 of 5
2. Question
Which of the following are considered as ‘Ecosystem Services’?
- Pollination of crops
- Prevention of soil erosion
- Water purification
- Decomposition of wastes
- Climate Regulation
Select the correct code:
Correct
Solution: d)
Ecosystem services are the many and varied benefits that humans freely gain from the natural environment and from properly-functioning ecosystems. Collectively, these benefits are becoming known as ‘ecosystem services’, and are often integral to the provisioning of clean drinking water, the decomposition of wastes, and the natural pollination of crops and other plants.
Ecosystem services are grouped into four broad categories: provisioning, such as the production of food and water; regulating, such as the control of climate and disease; supporting, such as nutrient cycles and oxygen production; and cultural, such as spiritual and recreational benefits.

Question 3 of 5
3. Question
Consider the following statements regarding Renewable Energy Policy Network for the 21st Century (REN21)
- REN21 is an international non-profit association and is based at International Solar Alliance (ISA).
- Its goal is to facilitate knowledge exchange, policy development and joint action towards a rapid global transition to renewable energy.
Which of the above statements is/are correct?
Correct
Solution: b)
REN21 is the global renewable energy policy multi-stakeholder network that connects a wide range of key actors. REN21’s goal is to facilitate knowledge exchange, policy development and joint action towards a rapid global transition to renewable energy.
REN21 brings together governments, nongovernmental organisations, research and academic institutions, international organisations and industry to learn from one another and build on successes that advance renewable energy. To assist policy decision making, REN21 provides high quality information, catalyses discussion and debate and supports the development of thematic networks.
REN21 is an international non-profit association and is based at the United Nations Environment Programme (UNEP) in Paris, France.

4. Question
Consider the following statements
- Aichi biodiversity targets was adopted at the Nairobi conference of the Convention on Biological Diversity (CBD).
- The IUCN Species Programme provides advice to Parties, other governments and partners on the implementation of Aichi Biodiversity Targets.
Which of the above statements is/are correct?
Correct
Solution: b)
The ‘Aichi Target’ adopted by the Convention on Biological Diversity (CBD) at its Nagoya conference. In the COP-10 meeting, the parties agreed that previous biodiversity protection targets are not achieved,
The IUCN Species Programme provides advice to Parties, other governments and partners on the implementation of the Strategic Plan for Biodiversity and it’s Aichi Biodiversity Targets (2011 – 2020).

Question 5 of 5
5. Question
Consider the following statements regarding Black Carbon.
- Black carbon is the sooty black material emitted from gas and diesel engines, coal-fired power plants, and other sources that burn fossil fuel.
- Black carbon has an atmospheric lifetime of more than 100 years.
- Black carbon deposits in the Arctic increases the Earth’s ability to reflect the warming rays of the sun.
Which of the above statements is/are correct?
Correct
Solution: b)
Black carbon is the sooty black material emitted from gas and diesel engines, coal-fired power plants, and other sources that burn fossil fuel. It comprises a significant portion of particulate matter or PM, which is an air pollutant.
Black carbon is a global environmental problem that has negative implications for both human health and our climate. Inhalation of black carbon is associated with health problems including respiratory and cardiovascular disease, cancer, and even birth defects. Black carbon also contributes to climate change causing changes in patterns of rain and clouds.
As black carbon deposits in the Arctic, the particles cover the snow and ice, decreasing the Earth’s ability to reflect the warming rays of the sun, while absorbing heat and hastening melt.
Black carbon stays in the atmosphere for only several days to weeks, whereas carbon dioxide (CO2) has an atmospheric lifetime of more than 100 years.
