Q.1	A scientist is monitoring the water quality of a lake used for recreational activities. She observes a sudden increase in the lake's phytoplankton population, followed by a decrease in the DO level and a rise in fish mortality. This phenomenon is most likely due to:

Q.2	Biodiversity loss due to deforestation can have a cascading effect on the ecosystem. Which of the following is the LEAST likely consequence of widespread species extinction?

Q.3	You're passionate about reducing your environmental footprint, particularly concerning packaging materials. You've come across a study that highlights the significance of recycling and reuse in lessening the environmental impact of packaging. Which of the following statements accurately reflects the environmental impact of recycling and reuse in relation to packaging materials?

Q.4	A small community in a rural area relies on a well for its drinking water. However, recent tests have shown that the well water is contaminated with bacteria. The community is concerned about the health risks posed by the contaminated water and is considering various options for addressing the problem. Which of the following options would be the most effective, sustainable and long-term solution for the community to protect its drinking water source? 1. Install a water filtration system at the well. 2. Educate the community about the importance of proper sanitation practices. 3. Find a new source of drinking water, such as a bottled water supplier.

Q.5	In a region prone to erratic weather patterns, farmers face the recurring challenge of water scarcity. A group of agricultural researchers suggests adopting sustainable practices to mitigate the effects of drought. What would be the most effective way to implement this solution?

Q.6	Consider the case study given below and answer the following question: Title: Forests as Crucial Carbon Capture Systems Forests play a critical role in mitigating climate change by capturing and storing carbon dioxide from the atmosphere. Trees absorb carbon dioxide through photosynthesis and use it to grow. The carbon is then stored in the tree's biomass (wood, leaves, branches, and roots) and soil. Forests also help to regulate the climate by releasing water vapour into the atmosphere, which can form clouds and reflect sunlight back into space. Trees are the most significant carbon sink in forests, storing carbon in their biomass. The amount of carbon stored in a tree depends on its species, size, and age. Young forests capture carbon rapidly due to the quick growth of trees. Middle-aged forests store relatively greater amounts of carbon as trees grow slower but sequester more carbon. Old-growth forests contain large trees that retain carbon for extended periods, albeit at a slower rate due to fewer trees overall. Forest soils contain diverse forms of carbon influenced by soil type, vegetation, and geography. Soil properties, such as high organic content or frozen conditions, significantly impact carbon storage potential. The carbon captured by forests is eventually returned to the atmosphere through processes like decomposition and respiration. Different forest types exhibit varying rates of carbon capture and release. Tropical forests capture carbon rapidly but can release it quickly too. In contrast, temperate forests offer a balanced solution. Effective management strategies, such as forest preservation, sustainable forestry practices, forest expansion, and invasive species control, are crucial in optimising carbon sequestration potential while maintaining ecosystem balance. A farmer is contemplating converting a section of their farmland into a forest to optimise carbon sequestration potential. Which set of actions would best help the farmer achieve this goal? 1. Plant a mix of tree species known for fast growth and high carbon storage capacity. 2. Plant trees that are native to the region. 3. Leave the soil unplanted and unattended to encourage natural regeneration of native vegetation.

Q.7	You're a municipal waste manager responsible for handling electronic waste (e-waste) in your city. During a routine inspection of the e-waste disposal facility, you notice a significant amount of discarded electronic devices, including computers, monitors, and smartphones. Concerned about potential health hazards, you decide to educate the public about the risks associated with improper disposal of these devices. Which of the following group of heavy metals is commonly found in electronics and can pose serious health risks if not properly disposed of?

Q.8	A scientist is studying the effects of climate change on a tropical rainforest. She measures the amount of water vapour in the atmosphere and finds that it has increased by 10% over the past decade. What does this suggest?

Q.9	A rural village has limited access to electricity, relying primarily on kerosene lamps for lighting. Kerosene use has been linked to respiratory problems and indoor air pollution. The village council is considering ways to improve access to clean and reliable electricity. Which of the following would be the most effective long-term solution to address both health concerns and energy needs?

Q.10	Consider the case study given below and answer the following question: Case study: Combatting Global Food Waste In a study conducted by the World Resources Institute, it was estimated that one-third of all food produced globally is wasted. This staggering amount represents a significant loss of resources, including water, land, and energy, and contributes to greenhouse gas emissions. To address this pressing issue, researchers have developed various strategies to reduce food waste, each tailored to specific stages of the food supply chain. At the household level, meal planning and proper storage practices can significantly reduce food waste. Planning meals ahead of time helps individuals avoid impulse purchases and ensures that ingredients are used before they spoil. Proper storage, such as keeping fruits and vegetables in the refrigerator and storing pantry items in airtight containers, extends the shelf life of food. In the retail sector, implementing innovative technologies like dynamic pricing and smart packaging can help reduce food waste. Dynamic pricing adjusts the price of perishable items based on their freshness, encouraging consumers to purchase items before they spoil. Smart packaging incorporates sensors that monitor the freshness of food, alerting retailers when items are nearing their expiration dates. Food waste reduction strategies also extend to the production and processing stages of the food supply chain. Improved harvesting techniques and post-harvest handling practices can minimise damage to crops and reduce food losses. Additionally, diverting inedible food scraps from landfills to composting facilities can convert waste into valuable nutrient-rich soil amendments. By implementing these strategies at various stages of the food supply chain, we can collectively reduce food waste, conserve resources, and minimise our environmental impact. Based on the scenario provided, which statement best summarises the overall impact of the food waste reduction initiative? 1. Food waste reduction conserves resources and minimises environmental impact. 2. Food waste reduction improves food security and reduces hunger. 3. Food waste reduction promotes sustainable agriculture and economic growth.
