Q.1	Boreal forests, found predominantly in the Northern Hemisphere, play a significant role in global carbon storage. How do the cold temperatures in these regions affect carbon storage in boreal forests?

Q.2	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.3	An environmental organisation has embarked on a project aimed at restoring a degraded river ecosystem. The project involves reintroducing native fish species that have declined due to habitat degradation and water quality issues. Additionally, efforts are being made to improve overall water quality by implementing measures to reduce pollution and restore natural habitat. What could be an anticipated outcome of this restoration effort in the degraded river ecosystem?

Q.4	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.5	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.6	John is considering installing a heating and cooling system in his new home. He wants an energy-efficient and environmentally friendly option. After researching various systems, he learned about geothermal heat pumps. Which of the following statements is true about geothermal heat pumps? 1. Geothermal heat pumps use the Earth's constant temperature to heat and cool homes. 2. Geothermal heat pumps maintain consistent efficiency in all weather conditions. 3. Geothermal heat pumps have a longer lifespan than traditional systems.

Q.7	A bustling city faces challenges with its growing wastewater volume and outdated treatment facilities. This untreated wastewater is discharged into a nearby river, leading to algal blooms, low oxygen levels, and fish die-offs. Complete the flowchart by accurately identifying the specific methods and techniques A, B and C utilised in primary, secondary, and tertiary wastewater treatment aimed at enhancing the quality of discharged water.

Q.8	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?

Q.9	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?

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.
