Answer:
Different types of macro organisms live in different qualities of water. This is because some are more resistant to pollution than others. For example, leeches and aquatic worms thrive in polluted water. Others are very sensetive to it, such as Mayflies, Caddisflies and Stoneflies.
To prevent water pollutions, you can be careful about what goes down your drains. All water from your drain has to re-enter the ecosystem at some point. Pouring oil, fat or grease down the sink is a very bad thing for the environment.
Water is important because we need a healthy water supply to keep our communities healthy. If our water supply such as a river or lake is contaminated with pollutants, it will become undrinkable.
For H2O(l) at 100 ∘C, d=0.958gcm−3 and ΔvapH=40.7kJmol−1.

Copper is a heavy metal that can harm many people. This process of heavy metals building in your body is called bioaccumulation and the process of this building in the food chain is called biomagnification. Its hard to rid of this heavy metal because it is very dense, therefore, cannot breakdown in our bodies. Heavy metals get consumed by producers and then reach to the top of the pyramid (us) so we have the highest risk of getting diseases and so on. Make sure you explain that heavy metals get passed from industrial purposes where companies do not dispose of waste properly.
