Q.1	A research team investigated the effects of climate change on the migration patterns of marine species. What implications can changing migration patterns have on marine ecosystems, and how might this impact human communities reliant on these species for sustenance?
	a) Altered migration patterns might disrupt food chains, affecting species abundance and diversity in marine ecosystems		b) Changing migration patterns will have no significant impact on marine ecosystems
	c) Human communities relying on these species can easily adapt to changes in migration patterns		d) Altered migration patterns will lead to increased catch and abundance of marine species, benefiting human communities

Q.2	You are tasked with designing a wastewater treatment plant. Which stage of the treatment process is responsible for removing solid particles from sewage water?
	a) Primary treatment		b) Secondary treatment
	c) Tertiary treatment		d) Chlorination

Q.3	In a biology class, students are discussing the various components of the water cycle. How does transpiration contribute to this natural process?
	a) It adds water vapour to the atmosphere from plant leaves.		b) It causes rainfall directly.
	c) It prevents the water cycle from functioning.		d) It decreases the humidity in the atmosphere.

	a) Plastic waste		b) Glass bottles
	c) Agricultural residues		d) Metal scraps

Q.5	Hannah is researching the environmental impact of food choices. She notices that a diet high in animal products contributes significantly to greenhouse gas emissions. What dietary change could Hannah suggest to her community to reduce this impact?
	a) Promoting a solely plant-based diet to eliminate greenhouse gas emissions.		b) Encouraging the consumption of more red meat and dairy products.
	c) Suggesting an increase in processed food consumption to reduce animal product intake.		d) Advocating for a balanced diet with moderate consumption of animal products.
