Question

How would the disposal of garbage affect the living organisms in the Ganga river

Answer 1

Answer:

Disposal of garbage in the Ganga river increases concentration of pollutants in the water. This kills the aquatic organisms.

Explanation:

• Garbage contains pollutants that are obnoxious, harmful, toxic and poisonous.
• They affect the aquatic ecosystem adversely.
• It can increase the BOD (Biochemical Oxygen Demand) of the water, thereby reducing dissolved oxygen concentration in the water. This can kill many aquatic organisms that are sensitive.
• It can also increase the nutrient composition of the water, that can result in algal blooming (excessive algal growth) resulting in death of other organisms (due to reduced food availability).
• It can also cause Bio-magnification, that is, the increase in toxic substance concentration in aquatic plant and animals.

Answer 2

Disposal of garbage affects the living organism

Explanation:

1. Repeated disposal of garbage which contain highly toxic materials can affect the aquatic organisms.
2. Eutropication occur that means increase of materials in the water body that lead to the formation of aquatic plants which in turn decrease the oxygen content in the water, and thus it causes negative impact on the health of fish.
3. Algal bloom occur which harms the aquatic lives as some algae secrete some harmful chemicals that are harmful for the fishes.
4. Toxic material that enter in the body of fish and when the intake of fish is done by a person, the toxic material enter into their body which creates diseases.
5. Due to increase level of garbage, the aquatic plants don't get proper sun light and thus they can't do photosynthesis.
