Q.1	In your research on marine ecosystems, you've found evidence suggesting shifts in the distribution of certain fish species. Fish that were once abundant in cooler waters are now migrating to different regions. What is the primary factor influencing this phenomenon?
	a) Changes in ocean salinity		b) Reduced predation in the new habitats
	c) Increasing acidity in the oceans		d) Rising ocean temperatures

Q.2	In a coastal region, oil spills are a common occurrence due to shipping activities. Which ecological consequence can be observed in the affected marine ecosystem?
	a) Increased biodiversity and thriving fish populations		b) Coral reefs growing rapidly to filter out oil contaminants
	c) Mass mortality of marine life and damage to habitats		d) Faster recovery of oil-impacted areas than non-impacted ones

Q.3	Sophie and her marine biology class were on a research vessel exploring marine life near the coast. Suddenly, they noticed a distressed pod of dolphins swimming amidst an oil slick that stretched for miles. Investigating further, they realised it was the result of a tanker accident, causing severe repercussions for the marine environment. Sophie and her classmates witnessed an oil spill from a tanker that affected the surrounding ocean. How does this type of marine pollution primarily impact marine ecosystems?
	a) It increases oxygen levels in the water, benefiting fish and other aquatic organisms.		b) It leads to increased biodiversity as some species adapt to the oil-rich environment.
	c) It accelerates coral reef growth due to the nutrients present in the oil.		d) It disrupts the food chain by poisoning primary producers like algae and plankton.

Q.4	Sarah is a teacher at an elementary school. She collects scrap paper from her students and uses the blank sides for drawing, thereby extending the life of the paper before recycling it. What is Sarah doing in this scenario to contribute to waste reduction and sustainability?
	a) Throwing scrap paper away		b) Promoting the use of new paper
	c) Reusing paper before recycling it		d) Increasing paper waste

Q.5	Your city throws away tons of food, leading to environmental issues and wasted resources. Two groups proposed solutions: Group A: "Community Kitchens": Establish kitchens that collect discarded food, prepare nutritious meals, and serve them to those facing hunger. "Urban Composting Network": Create a network of community composting bins and educational programs to turn food scraps into nutrient-rich soil for urban gardens. Group B: "Smart Fridges": Implement high-tech fridges that monitor food freshness and notify owners to prevent expired waste. "Automated Recycling Plants": Build specialised plants that efficiently process organic waste into fertilisers and renewable energy. Which group's approach do you think will more effectively reduce food waste and address related challenges? Why?
	a) Group A, because their solutions directly tackle hunger and soil depletion while utilising waste.		b) Group B, because their solutions focus on prevention and technological efficiency.
	c) Both groups offer complementary solutions, combining social impact with waste reduction and resource utilisation.		d) Neither group, as existing policies are sufficient to address food waste issues.

Q.6	Imagine you are an urban farmer in a city with limited space. Which farming method would be most suitable for your situation?
	a) Large-scale traditional farming		b) Vertical farming
	c) Expansive greenhouse farming		d) Aquaculture in open ponds

Q.7	A community introduced a new technology that reduced water usage for irrigation by 20%. Initially, 1,000 hectares of land were irrigated using 200,000 cubic meters of water. What volume of water would be saved annually if this technology is applied to all 1,000 hectares?
	a) 40,000 cubic meters		b) 20,000 cubic meters
	c) 160,000 cubic meters		d) 250,000 cubic meters

Q.8	Max was studying the Earth's atmosphere in class. He learned about a special layer that shields us from harmful solar radiation. While explaining it to his friend, Sarah, she asked, "What's the name of this protective layer?"
	a) Ionosphere		b) Exosphere
	c) Troposphere		d) Stratosphere

Q.9	A study in a river basin area shown in the picture reveals that the concentration of heavy metals in the water significantly exceeds permissible limits downstream of an industrial area. What can be inferred from this data?
	a) Heavy metals have no impact on water quality		b) The river basin acts as a natural filter, reducing pollution
	c) Industrial activities are likely the source of heavy metal pollution		d) The upstream area is more polluted due to urban development

Q.10	In a region rich with diverse wildlife, researchers are assessing the impact of habitat fragmentation on biodiversity. They explore different scenarios to understand how fragmentation influences the ecosystems. In which scenario would habitat fragmentation have the least impact on biodiversity?
	a) Small habitat areas fragmented into smaller patches far from each other.		b) Moderate-sized habitat areas fragmented into patches with varied distances between them.
	c) Large habitat areas fragmented into smaller patches close to each other.		d) Large habitat areas fragmented into larger patches far from each other.
