Q.1	A city is expanding its wastewater treatment infrastructure to improve the quality of treated water released into the environment. As part of this development, engineers and environmental experts are reviewing the different stages of wastewater treatment to ensure the most effective processing of sewage. In the wastewater treatment process, which stage involves the breakdown of organic matter by microorganisms in the absence of oxygen?
	a) Primary treatment		b) Secondary treatment
	c) Tertiary treatment		d) Anaerobic digestion

Q.2	A group of students studying ecology in a temperate forest notices a sharp decline in the local frog population. They discover that a new housing development has encroached upon a wetland area that was once home to a diverse array of amphibians. What is the likely consequence of the wetland habitat loss on the surrounding forest ecosystem?
	a) Disruption of food webs and energy flow, potentially impacting other animal populations.		b) An imbalance in the nitrogen cycle as frogs play a vital role in decomposing organic matter.
	c) Enhanced soil fertility and plant growth due to nutrient-rich runoff from the development.		d) Increased insect populations due to the absence of natural predators like frogs.

Q.3	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.4	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.5	A community experiences an outbreak of a waterborne disease called Amoebiasis, characterised by severe abdominal cramps, diarrhoea with blood, and high fever. Individuals affected report exposure to contaminated water sources. Identify the causative agent responsible for these symptoms.
	a) Entamoeba histolytica		b) Giardia lamblia
