Q.1	A group of conservationists is conducting a study in a coastal region known for its diverse ecosystem. They notice a significant decline in the population of native plant species due to the introduction of non-native plants by human activities. As they delve deeper into their research, they aim to assess the significance of native species within this ecosystem. What role do native species most likely play in this coastal ecosystem?
	a) Native species contribute minimally to the ecosystem compared to non-native species.		b) Native species only survive in isolated pockets and do not significantly impact the ecosystem.
	c) Native species offer cultural significance but have little ecological importance.		d) Native species are crucial for ecosystem stability, providing habitat and resources for various organisms.

Q.2	A community relies on a rainwater harvesting system for its water supply. The system collects rainwater from rooftops and stores it in large underground tanks. After a heavy rainfall, the residents notice that the stored water has a brownish colour and an unpleasant odour. What could be the most likely cause of this contamination? 1. Insufficient filtration and disinfection of the rainwater 2. Accumulation of organic debris in the storage tanks 3. Leaching of pollutants from roofing materials
	a) Only 1		b) Only 1 and 2
	c) Only 2 and 3		d) 1, 2 and 3

Q.3	A coastal area witnesses a significant decrease in the population of shellfish due to water contamination. Analysis reveals the presence of persistent organic pollutants (POPs). POPs are resistant to environmental degradation through chemical, biological, and photolytic processes. For this reason, they persist in the environment for a long time. Which method is most effective in reducing POPs in aquatic environments?
	a) Bioremediation with specialised bacteria		b) Bioaccumulation
