Q.1	In the dense, lush forests of the Amazon basin, researchers are studying the ecosystem's dynamics to understand its role in global environmental processes. Which specific layer of the forest ecosystem plays a crucial role in regulating carbon levels and atmospheric moisture?
	a) Canopy layer		b) Emergent layer
	c) Understory layer		d) Forest floor

Q.2	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. Imagine conducting an experiment measuring carbon sequestration rates in four different forest types over the span of a year. Based on your understanding of the case study, which forest type would you expect to demonstrate the highest rate of carbon capture per unit area within a year?
	a) Young temperate forest		b) Old-growth tropical forest
	c) Middle-aged temperate forest		d) Young tropical forest

Q.3	A major Himalayan glacier, a vital source of freshwater for millions downstream, is retreating at an alarming rate. Satellite imagery reveals a significant decrease in the glacier's mass over the past few years. Data also shows a connection between rising global temperatures and the accelerated melting of glaciers worldwide. Considering the scenario, which of the following is the most likely consequence of the glacier's retreat for the communities downstream?
	a) Increased hydropower generation due to higher water flow		b) Improved water quality
	c) Enhanced biodiversity in the surrounding ecosystem due to the release of nutrients		d) Water scarcity and competition for resources among communities

Q.4	Ecological restoration is the process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed. Which of the following is NOT a primary goal of ecological restoration?
	a) Reestablishing native plant and animal species to their original habitats		b) Restoring natural ecological processes and functions within the ecosystem
	c) Promoting the sustainable use of resources and reducing human impacts on the ecosystem		d) Enhancing the economic value and productivity of the restored land

Q.5	Satellites have documented the rapid retreat of glaciers in Antarctica and Greenland, contributing significantly to global sea level rise. In addition to coastal flooding, this melting ice could also:
	a) Lead to the discovery of new mineral resources beneath glaciers.		b) Disrupt ocean currents, impacting global weather patterns.
	c) Decrease the salinity of seawater, harming marine life.		d) Create vast new fishing grounds as previously frozen areas become accessible.

	c) It's produced using sustainable farming methods without synthetic pesticides or fertilisers.		d) It contains natural ingredients.

Q.7	You are troubleshooting a high electricity bill and notice that even when all appliances are turned off, the energy meter is still registering a small amount of power usage. This phenomenon is known as a vampire load. What is the main reason why vampire loads occur in most appliances?
	a) Appliances continue to draw a small amount of power even when they are turned off.		b) Appliances are not properly grounded, which causes them to leak electricity.
	c) Appliances are designed to be constantly turned on, so they use more energy when they are off.		d) Appliances are not properly connected to power outlets, which causes them to malfunction.

Q.8	Your city is considering expanding its aquaculture industry to meet the growing demand for seafood.
