	c) Membrane bioreactors		d) Flocculation

Q.2	A group of scientists studying the melting glaciers in Antarctica discovered ancient air bubbles trapped within the ice. Analysing these bubbles, they find significantly lower concentrations of carbon dioxide compared to the present atmosphere. This information suggests that:
	a) Human activities have significantly increased the concentration of carbon dioxide in the atmosphere.		b) The current levels of carbon dioxide are within the natural range of variation for Earth's climate.
	c) The melting glaciers are a major source of carbon dioxide emissions contributing to global warming.		d) Ancient civilisations had developed advanced technologies to capture and store carbon dioxide.

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

Debris accumulation in oceans primarily consists of organic waste, which enhances marine biodiversity by providing habitats for various species. 2. Sustainable aquaculture involves utilising antibiotics to control diseases and enhance fish growth in farms. 3. Coastal development and shoreline alterations significantly impact marine habitats or disrupt the natural flow of sediments in coastal areas. 4. Overfishing contributes to the creation of dead zones due to the imbalance in marine ecosystems caused by the removal of certain fish species.

Q.5	During a science fair, a student presented a project on the impact of wildfires on climate change. They highlighted that wildfires release vast amounts of carbon dioxide, methane and nitrous oxide into the atmosphere as shown in the table given below. What inference can be made from this presentation? 1. Wildfires can act as a positive feedback loop, contributing to further warming and potentially more frequent fires. 2. Wildfires are primarily responsible for the rising levels of greenhouse gases in the atmosphere. 3.
