Answer: Water pollution can have disastrous effects on the environment.
Explanation:
- Pollution in the water can reach a point where there isn't enough oxygen in the water for the fish to breathe. The fish can suffocate and not have enough air.
- Pollution affects the entire food chain. Small fishes absorb pollutants, such as chemicals, into their bodies. Bigger fishes eat the smaller fishes and get the pollutants as well. Birds or other animals may eat the bigger fishes and be harmed by the pollutants. One example of this was the use of the insecticide (bug killer) DDT, which is when birds of prey ate fishes that were infected with it, they would lay eggs with thin shells. The population of birds of prey began to drop until DDT was banished.
- Sewage causes major problems in rivers. Bacteria in the water will use oxygen to break down the sewage. If there is too much sewage, the bacteria could use up oxygen until there won't be enough left for the fish.
- Water pollution from major events like acid rain or oil spills can completely destroy marine habitats.
- One of the most important commodities for life on planet Earth is clean water. For over 1 billion people on the planet, clean water is nearly impossible to get. Dirty, polluted water can make them sick enough to die.
A simple stain is used to show that bacteria is present and what they look like opposed to other matter. a differential stain is used to separate organisms into groups.
Answer: True
Explanation:
Eutrophication is a natural phenomena, in this the fertilizers which are rich in concentration of nitrogen and phosphorus due to the effect of surface runoff get deposited in the nearby water body such as river, lake, pond and others. These fertilizers facilitate the growth of aquatic plants in the water body. The excess growth of plants reduces the oxygen content of the water body, which results in decline in the population of aquatic animals and foul smell in water.
