Q.1	A group of environmental scientists conducted a study on the significance of land-based environments in maintaining ecological balance. They explored various aspects ranging from biodiversity to human reliance on terrestrial ecosystems. During their research, the scientists observed a correlation between land-based environments and the overall health of marine ecosystems. Choose an appropriate option that best reflects the importance of terrestrial ecosystems for marine life.
	a) Land-based environments have minimal impact on marine ecosystems, thus their significance is negligible.		b) Terrestrial environments act as a buffer, filtering pollutants before they reach the oceans, thus preserving marine habitats.
	c) Marine ecosystems are entirely independent of land-based environments, having no ecological connections.		d) Human activities in terrestrial ecosystems do not affect the quality of water in marine environments.

Q.2	In a coastal city, citizens are concerned about the decreasing number of mangrove forests. What role do mangrove forests play in protecting marine ecosystems, and how can their depletion harm marine life?
	a) Mangroves prevent erosion and provide habitats; their depletion can lead to loss of breeding grounds for fish and increased coastal erosion		b) Mangroves absorb excess nutrients; their depletion can lead to overgrowth of marine plants and decreased oxygen levels in water
	c) Mangroves reduce ocean acidity; their depletion can lead to coral bleaching and loss of biodiversity		d) Mangroves filter pollutants; their depletion has no significant impact on marine life

Q.3	A research team investigated the effects of climate change on the migration patterns of marine species. What implications can changing migration patterns have on marine ecosystems, and how might this impact human communities reliant on these species for sustenance?
	a) Altered migration patterns might disrupt food chains, affecting species abundance and diversity in marine ecosystems		b) Changing migration patterns will have no significant impact on marine ecosystems
	c) Human communities relying on these species can easily adapt to changes in migration patterns		d) Altered migration patterns will lead to increased catch and abundance of marine species, benefiting human communities

Q.4	An agricultural study highlighted the impact of changing climate on crop yields, showing a decline in productivity due to irregular rainfall patterns. What is the primary consequence of irregular rainfall patterns on agricultural productivity?
	a) Increased soil nutrient retention		b) Greater crop resilience to weather fluctuations
	c) Reduced water stress on crops		d) Yield losses due to water scarcity and drought

Q.5	A community in a rural area is facing water quality issues due to the presence of microbial contaminants in their water supply. Which of the following water treatment methods would be the most effective in removing microbial contaminants and ensuring safe drinking water for the entire community?
	a) Filtration		b) Boiling
	c) Chlorination		d) Distillation

Q.6	Your once-sunny city seems shrouded in a hazy cloud of smog, especially during winter. Cars and factories are the main culprits, but everyone suffers from breathing difficulties and reduced visibility. Which air pollutants from fossil fuels are likely contributing to this smog, and how can your city combat these issues?
	a) Nitrogen dioxide and sulphur dioxide from vehicle exhausts and factory emissions combine with sunlight to form harmful smog, which can be tackled by promoting electric vehicles and stricter emission regulations.		b) Carbon dioxide, the main greenhouse gas from fossil fuels, directly contributes to smog, and the solution lies solely in switching to renewable energy sources like solar and wind.
	c) Fine particulate matter from car dust and industrial activities traps pollutants in the air, worsening smog. Investing in public transportation and green spaces can alleviate the problem.		d) Smog is primarily caused by natural phenomena like dust storms and forest fires, and the city should focus on preparing for these events rather than blaming fossil fuels.
