$(i)$ An increase in temperature of the water bodies would lead to water pollution: Explain.
$(ii)$ Suggest any two methods to prevent water pollution.

(N/A) $(i)$ An increase in the temperature of water bodies leads to water pollution because it reduces the amount of dissolved oxygen available for aquatic organisms. Furthermore,many aquatic species are sensitive to temperature changes; higher temperatures can kill eggs and larvae,disrupt reproductive cycles,and alter the ecological balance of the ecosystem.
$(ii)$ Two methods to prevent water pollution are:
$1$. Do not dispose of industrial or domestic waste directly into water bodies.
$2$. Avoid washing clothes or bathing animals at river banks to prevent detergents and contaminants from entering the water.
