Question 1 of 5
1. Question
Consider the following statements.
- Sudden and unpredictable change in the species composition of a given area is called ecological succession.
- During succession some species colonise an area and populations of other species decline and even disappear.
Which of the above statements is/are correct?
Correct
Solution: b)
The gradual and fairly predictable change in the species composition of a given area is called ecological succession. During succession some species colonise an area and whereas populations of other species decline and even disappear.
Incorrect

Question 2 of 5
2. Question
Consider the following statements.
- The composition and structure of all communities constantly change in response to the changing
environmental conditions.
- Community that is in near equilibrium with the environment is called a climax community.
- The change in the composition and structure of the communities is not dependent with the changes in the physical environment.
Which of the above statements is/are correct?
Correct
Solution: a)
An important characteristic of all communities is that their composition and structure constantly change in response to the changing environmental conditions. This change is orderly and sequential, parallel with the changes in the physical environment. These changes lead finally to a community that is in near equilibrium with the environment and that is called a climax community.

Question 3 of 5
3. Question
Consider the following statements.
- The entire sequence of communities that successively change in a given area are called sere.
- The present-day communities in the world is because of succession that has occurred over millions of years.
- Succession is not possible in an area where there is no living Organisms.
Which of the above statements is/are correct?
Correct
Solution: c)
The entire sequence of communities that successively change in a given area are called sere(s).
The present-day communities in the world have come to be because of succession that has occurred over millions of years since life started on earth. Actually, succession and evolution would have been parallel
processes at that time.
Succession is hence a process that starts in an area where no living organisms are there – these could be areas where no living organisms ever existed, say bare rock; or in areas that somehow, lost all the living
organisms that existed there. The former is called primary succession, while the latter is termed secondary succession.

Question 4 of 5
4. Question
The formation of ozone hole in the Antarctic region has been a cause of concern. What could be the reason for the formation of this hole?
Correct
Solution: d)
Polar Stratospheric Clouds or nacreous clouds contain water, nitric acid and/or sulfuric acid.
They are formed mainly during the event of polar vertex in winter; more intense at south pole.
The Cl-catalyzed ozone depletion is dramatically enhanced in the presence of polar stratospheric clouds (PSCs).

Question 5 of 5
5. Question
Consider the following statements about Global Footprint Network.
- The Global Footprint Network is an attached office of UNEP, promoting and driving sustainable policy decisions.
- Global Footprint Network’s goal is to create a future where all humans can live well, within the means of one planet Earth.
- Global Footprint Network calculatesEarth Overshoot Day every year.
Which of the above statements is/are correct?
Correct
Solution: b)
The Global Footprint Network is an international think tank promoting and driving sustainable policy decisions in a world of limited resources. Together with its various partners, Global Footprint Network (GFN) coordinates research, develops methodological standards, and provides decision makers with a menu of tools to help the human economy operate within Earth’s ecological limits.
Global Footprint Network calculates Earth Overshoot Day every year using Ecological Footprint accounting, which adds up all of people’s competing demands on nature, including demand for food, timber, and fibers (cotton); absorption of carbon emissions from burning fossil fuels; and buildings, roads and other infrastructure. August 1 is the earliest Earth Overshoot Day since the world went into ecological overshoot in the 1970s.
The Global Footprint Network was founded in 2003 with the aim to safeguard a sustainable world for all people in which they can live a fulfilled life within natural ecological boundaries. The headquarters of the Global Footprint Network is located in Oakland (USA), with further offices in Switzerland, Belgium and the Philippines.
