Q.1	In the Arctic, the habitat of polar bears, the ice is melting due to changing weather patterns. What might be the consequence for the polar bears?
	a) Increased availability of hunting grounds.		b) Decline in access to their primary food sources.
	c) Expansion of their natural habitat.		d) Decreased risk of extinction

Q.2	Why are oceans considered the "lungs of the Earth"?
	a) Because they produce a significant portion of the world's oxygen through phytoplankton photosynthesis		b) Because they are a source of clean air for the planet
	c) Because they release carbon dioxide into the atmosphere		d) Because they help in the transportation of oxygen to land-based ecosystems

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

Q.4	Blair's family always uses reusable shopping bags and avoids buying bottled water. They also eat mostly plant-based meals and compost food scraps. Serena's family uses plastic bags, drinks bottled water, and throws away food scraps. Select the statement(s) that accurately shows how Blair and Serena's families' consumption affects the environment. 1. Blair's family uses less plastic, reducing pollution and resource depletion. 2. Blair's family consumes more energy due to using reusable bags. 3. Blair's family contributes more greenhouse gases through plant-based meals. 4. Serena's family has a smaller environmental footprint because they buy less.
