1. Question
With reference to Interspecific interactions, which among the following is an example of Ammensalism?
CorrectAmmensalism: Amensalism is any relationship between organisms of different species in which one organism is inhibited or destroyed while the other organism remains unaffected. A common example of amensalism is the release of chemical toxins by plants that can inhibit the growth of other plant species

2. Question
With reference to Methane, which among the following statements is incorrect?
CorrectWhy is Methane Harmful?
• Methane is the simplest hydrocarbon, consisting of one carbon atom and four hydrogen atoms (CH4) – it is also flammable, and is used as a fuel worldwide apart from being a powerful greenhouse gas.
• Methane is 84 times more potent than carbon and doesn’t last as long in the atmosphere before it breaks down. This makes it a critical target for reducing global warming more quickly while simultaneously working to reduce other greenhouse gases.
• It is responsible for creating ground-level ozone, a dangerous air pollutant.IncorrectWhy is Methane Harmful?

3. Question
A shallow body of water separated from a larger body of water by barrier islands or reefs is called?
CorrectLagoons: A lagoon is a shallow body of water separated from a larger body of water by barrier islands or reefs.
Estuary: An estuary represents a boundary between rivers and the sea.
Gulf: The gulf is a large body of water that penetrates the land. It is generally larger than a bay and connects the land and sea.
Strait: A strait is a naturally formed, narrow, typically passable waterway that connects two larger bodies of water.

4. Question
Consider the following statements about Bioremediation
1) It is the use of non-indigenous living organisms to degrade the environmental contaminants or pollutants into less toxic forms.
2) For bioremediation to be effective microorganisms must enzymatically attack the pollutants and convert them to harmless products.
Which of the following statements is/are correct?
CorrectBioremediation is the use of living organisms primarily microorganisms to degrade the environmental contaminants or pollutants into less toxic forms. It uses naturally occurring bacteria and fungi or plants to degrade or detoxify substances hazardous to human health and the environment. The microorganisms may be indigenous to a contaminated area or they may be isolated from elsewhere and brought to the contaminated site. Hence statement 1 is incorrect.
Contaminant compounds are transformed by living organisms through reactions that take place as a part of their metabolic processes. For bioremediation to be effective microorganisms must enzymatically attack the pollutants and convert them to harmless products. Hence statement 2 is correct.

5. Question
Consider the following statements about Photochemical smog
1) Photochemical smog occurs in a cool, humid climate.
2) The primary pollutants that contribute towards photochemical smog include oxides of nitrogen
3) It results in the formation of ground level ozone
Select the correct answer using the code given below.
CorrectPhotochemical smog occurs in warm, dry and sunny climate. A classical smog occurs in cool humid climate. Hence statement 1 is incorrect.
Common examples of primary pollutants that contribute towards photochemical smog include oxides of nitrogen such as nitric oxide, nitrogen dioxide, and nitrous oxide and most VOCs (volatile organic compounds). Hence statement 2 is correct.
These reactions often result in the formation of ground level ozone and certain airborne particles. Hence statement 3 is correct.
