Which action will conserve aquatic organisms?

Answer and explanation

Correct answer: Protecting clean water sources

The direct answer is D: protecting clean water sources. Aquatic organisms live in rivers, lakes, ponds, wetlands, seas or other water environments, so clean and sufficiently available water is essential for their survival. Pollution can poison organisms, reduce oxygen, damage eggs and plants, and disturb food chains. Protecting water sources includes preventing waste dumping, treating sewage, controlling chemicals and maintaining natural habitats around water bodies. Option D is correct because it directly protects the environmental condition aquatic life needs. Option A, throwing waste into a river, causes pollution and may injure or kill aquatic organisms. Option B, spreading chemical pollution, can poison water and disturb reproduction and food chains. Option C, drying water bodies, removes the habitat and water supply altogether. Thus A, B and C are harmful actions, while D is a conservation action. The reasoning is simple: aquatic life needs clean water; protection maintains that water; therefore aquatic organisms are conserved. Memory cue: clean water means living water; never treat rivers as dustbins.
