Q.1	Considering the impact of climate change, which of the following species is likely to face the highest risk of endangerment? 1. A migratory bird species 2. A deep-sea fish species 3. A reptile species in a tropical forest
	a) Only 1		b) Only 1 and 2
	c) Only 2 and 3		d) 1, 2 and 3

Q.2	In a particular forest, a new road was constructed, splitting the area into two smaller sections. This resulted in isolating a group of endangered species to one side. What phenomenon does this scenario represent?
	a) Deforestation		b) Habitat fragmentation
	c) Overexploitation		d) Pollution

Q.3	Maria, a marine biologist, conducted a study in a coastal area. She noticed a decline in the population of a specific species of fish. Further research revealed that the rising ocean temperatures were affecting their breeding grounds. Which of the following best explains how increased ocean temperatures impact fish populations?
	a) Elevated temperatures facilitate better breeding conditions for fish.		b) Higher temperatures decrease predator's presence, causing a decline in fish populations.
	c) Increased ocean temperatures reduce oxygen levels, affecting fish reproduction.		d) Warmer temperatures encourage the migration of fish to colder regions for breeding.

Q.4	Consider a scenario where a city implements extensive water conservation methods, reducing wastewater released into rivers by 40%. If initially, 1,000 cubic meters of wastewater flowed into rivers per day, what would be the new daily volume released after conservation efforts?
	a) 1,400 cubic meters		b) 350 cubic meters
	c) 600 cubic meters		d) 400 cubic meters

Q.5	In a water quality testing experiment, you're examining a water sample. Upon adding a specific reagent to the sample, it turns blue. What does the colour change of the water sample indicate about its quality in this experiment?
	a) Presence of CO2		b) Neutral pH
	c) High chlorine content		d) Presence of ammonia

Q.6	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.7	A restaurant implements some new practices in their kitchen, such as using a dishwasher efficiently and fixing leaks promptly. What impact does this have on their overall sustainability?
	a) It has no effect on sustainability.		b) It reduces water consumption and contributes positively to sustainability.
	c) It increases water wastage and negatively affects sustainability.		d) It solely improves the restaurant's kitchen hygiene but doesn't impact sustainability.

Q.8	During a class project on ocean ecosystems, a student argued that overfishing only affects fish populations and doesn't influence other marine organisms. Which statement provides the most accurate perspective on this issue?
	a) Overfishing primarily affects larger fish species.		b) Overfishing is beneficial as it controls predator populations.
	c) Overfishing can disrupt the entire marine food web.		d) Overfishing has no significant impact on marine ecosystems.

Q.9	What is the primary function of a hydroelectric power plant in generating electricity?
	a) Converting water flow into mechanical energy that directly powers turbines.		b) Storing water in reservoirs to control floods and generate electricity simultaneously.
