Q.1	During a school project on recycling, Emma was tasked with investigating the environmental benefits of recycling aluminium cans versus manufacturing new ones. Which of the following statements is true regarding this comparison? 1. Recycling aluminium cans saves energy but does not reduce pollution. 2. Manufacturing new aluminium cans consumes less energy than recycling them. 3. Recycling aluminium cans reduces energy consumption and environmental pollution. 4. Manufacturing new aluminium cans have no impact on energy consumption or pollution.
	a) Only 1		b) Only 2
	c) Only 3		d) Both 1 and 4

Q.2	Consider the given pie chart representing energy consumption for a household. If the household wants to reduce its energy consumption significantly, which of the following measures should be prioritised based on the data provided?
	a) Upgrading to incandescent light bulbs		b) Unplugging appliances when not in use
	c) Improving insulation and using smart thermostats for heating/cooling		d) Using appliances with one-star rating

Q.3	In a study assessing greenhouse gas emissions in the food production sector, researchers analysed various contributing factors. Which factor most likely contributes most significantly to greenhouse gas emissions?
	a) Land clearing for agricultural purposes		b) Fertiliser use
	c) Livestock production		d) Irrigation practices

Q.4	In a coastal ecosystem, the population of shellfish declines drastically due to contamination by harmful algae producing toxins. What type of pollution is this?
	a) Thermal pollution		b) Nutrient pollution
	c) Chemical pollution		d) Biological pollution

Q.5	A group of scientists is studying the effects of climate change on a mountain grassland ecosystem. They observe that the average temperature in the region has increased over the past few decades, and that the timing of plant flowering has shifted earlier in the spring. How might these changes impact the interactions between plants and pollinators in this ecosystem?
	a) Pollinators may have difficulty finding food sources due to the mismatch between their life cycle and the timing of plant flowering, also resulting in reduced pollination success.		b) Pollinators may benefit from the increased temperature, as it could lead to an increase in plant growth and nectar production.
	c) Earlier plant flowering may have no significant impact on pollinators as they can adapt their behaviour and life cycles accordingly.		d) The rise in temperature could decrease the number of plant species, thereby reducing the variety of resources available for pollinators, causing a decline in their populations.

Q.6	In a future scenario where climate change drastically alters global weather patterns, which land biome would likely experience the MOST drastic and irreversible changes?
	a) A temperate deciduous forest with distinct seasonal variations.		b) A vast and diverse tropical rainforest with abundant rainfall.
	c) A fragile arctic tundra bordering on polar ice sheets.		d) A sprawling grassland with resilient and adaptable plant communities.

Q.7	A conservationist is concerned about the declining population of a particular endangered species in a forest reserve. What would be the most appropriate action to conserve this species?
	a) Introducing a different species to the reserve to enhance biodiversity.		b) Removing some competing species to give the endangered species more resources.
	c) Keeping the endangered species safe in captivity.		d) Conducting habitat restoration and protection efforts specific to the species' needs.

Q.8	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.

Q.9	Javier studied the adaptations of desert organisms. He discovered that certain desert plants have shallow roots but spread extensively. What advantage do these shallow, widespread roots offer to desert plants?
	a) Improved access to underground water sources.		b) Protection from extreme heat and sunlight.
	c) Enhanced stability in sandy soil.		d) Reduced reliance on photosynthesis for survival.

Q.10	In an area facing increased soil erosion due to extreme weather events linked to climate change, farmers seek strategies to protect soil health. What practice aligns best with sustainable soil management in such conditions?
	a) Clearing land for larger-scale monoculture to simplify farming practices.		b) Implementing agroforestry systems to prevent soil erosion and maintain fertility.
	c) Relinquishing organic matter addition to soil for fear of further erosion.		d) Applying chemical pesticides extensively to eradicate soil-dwelling pests.
