Answer 1

Answer: (C)

Water provides habitat to many organisms. Certain chemicals and pesticides contaminate the water badly and waste the water as well. The animals and plants inhabiting such water are affected and so are the animals who feed on them. Many bird visitors are also affected. One such chemical is lead.

So, the correct answer is 'Lead poisoning'.
