What could happen to the organisms that live in a fast-moving river if a dam were built on the river?
1 Answer
The physical State of water will instantly change. Changing the Habitat of the Aquatic plants and animals of that area.
Explanation:
The Plants or animals living in the area will certainly be affected by the sudden change in their habitat. They would go -
- Fresh water => Dammed water.
- Fast moving water => Still water.
- Daily changing water ==> Still or Stopped water.
- Hygienic water ==> Unhygienic water.
Their habitat now could even be affected by Protozoans and other parasites such as- Amoeba, Paramecium. Mosquitoes, Flies etc.
The place or water will now start gathering Phytoplankton and immense phytoplankton cover could even make the aquatic animal suffocate and die out of breath.
The dams will also not make the water flow as it flowed before so the water collected in the reservoir would get heated up fast and for longer time, this would make the temperature of the river rise up due to which many the aquatic life of that river would be damaged at a very much high rate.
Changing your Habitat Instantly is certainly not plausible.
Hope it Helps!!
