Q.1	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.2	Amelia observed that during heavy rains, one part of the city experienced flash floods and drainage issues due to excessive concrete, while another region with abundant green spaces remained relatively unaffected. Why did the area with green spaces fare better?
	a) The city's overall topography favored water runoff in green spaces.		b) Concrete areas had more efficient drainage systems in place.
	c) Green spaces effectively absorbed excess water, preventing flooding.		d) The presence of concrete minimised water absorption, causing flooding.

Q.3	You aim to reduce your carbon footprint through dietary changes. Which dietary adjustment would have the most significant positive impact based on their respective average annual carbon footprint?
	a) Consuming more red meat		b) Eating locally sourced produce
	c) Reducing food waste		d) Choosing plant-based proteins

Q.4	Using the information from the table, deduce the most likely observable consequence in a marine ecosystem. Consider the combined effects on the marine food chain and other species interactions. Pollutant Impact on Marine Species Oil Coats and suffocates marine birds Plastic Causes entanglement and ingestion isues in sea animals Heavy Metals Lead to biomagnification in marine food chains Nutrients Result in algal blooms and dead zones
	a) A decrease in marine bird populations due to suffocation		b) A reduction in sea animal entanglement and ingestion issues
	c) A significant drop in algal blooms and dead zones		d) An amplification of heavy metal concentration in top predators

Q.5	Analyse the graph below representing the water consumption patterns of a city over five years. Identify the trend in water consumption and propose a hypothesis explaining the observed pattern.
	a) Increasing trend; population growth leading to higher demand		b) Fluctuating trend; changes in climate affecting water availability
	c) Decreasing trend; successful implementation of water conservation measures		d) Stable trend; consistent water usage habits in the community

Q.6	Maya and Ethan analyse a table showing the decline of multiple endangered species, each facing different threats. Based on the table, which of the following conservation strategies would likely be MOST effective for protecting ALL of the listed species?
