Q.1	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

Q.2	What impact does population growth have on food security? 1. Increased population reduces food demand 2. Larger populations have no effect on food production 3. Rapid population growth can strain food resources 4. A growing population guarantees surplus food production
	a) Only 1		b) Only 3
	c) Both 2 and 3		d) Both 3 and 4

Q.3	Tom and Lily were thinking about different sources of energy for their home. Which options are renewable energy sources? 1. Coal and natural gas 2. Solar energy and wind energy 3. Hydro energy and geothermal energy
	a) Only 1		b) Only 3

	a) Rain		b) Fog
	c) Hail		d) Snow

Q.5	In a grassland food web experiment, researchers introduced a new herbivore species not native to the area. This herbivore consumed a wide range of plants. What is the most likely impact of introducing this herbivore on the grassland food web?
	a) An increase in plant diversity due to reduced herbivory		b) A decrease in the populations of native herbivores
	c) An increase in the populations of top predators		d) No significant impact on the food web structure
