Q.1	A tourist is exploring a kelp forest. What is the primary benefit of kelp forests in the marine ecosystem?
	a) Kelp forests have no impact on providing food and shelter for various marine species		b) Kelp forests do not assist in absorbing excess carbon dioxide from the atmosphere
	c) Kelp forests have no connection to maintaining the balance of marine food webs		d) Kelp forests provide habitats for numerous marine organisms and contribute to nutrient cycling

Q.2	You're studying the growth of a colony of rabbits in a field near a factory. You notice that the rabbits are smaller and less healthy than rabbit populations in other areas. What could be the reason for this?
	a) The factory is emitting noise pollution, disrupting the rabbits' sleep and breeding.		b) The factory is dumping chemicals into the soil, contaminating the plants the rabbits eat.
	c) The factory is attracting predators to the area, putting the rabbits at risk.		d) The factory is changing the climate of the area, making it less suitable for rabbits.

Q.3	A study analysed water samples from a polluted lake and found high levels of heavy metals such as lead and mercury. What is the potential impact of these heavy metals on the ecosystem of the lake?
	a) Heavy metals can accumulate in organisms and disrupt the food chain		b) Heavy metals can promote biodiversity and enhance ecosystem health
	c) Heavy metals have no effect on the lake ecosystem		d) Heavy metals can purify the lake water
