why does the increased level of nutrients in the water affect the survival of Aquatic organisms?
Answers
The increased level of nutrients in water helps aquatic animals in their survival because dissolved oxygen is taken in by algae and many types of plants.
Micro-organisms and plants of many types benefit from the same and aquatic life is held together in a proper way to a large extent.
Because of this reason, there is generally a lack of dissolved oxygen for all types of animals that live in it.
Answer:
is
Explanation:
Excessive quantities of chemicals (fertilizers, weedicides,insecticides, pesticides etc.) get washed away from the fields entering into water bodies like ponds,rivers,sea.
These act as nutrients for algae to flourish.
Once these algae die, they serve as food for decomposers like bacteria.
In this process a lot of oxygen in water gets used up.
This results in a decrease in the oxygen level for the aquatic organisms.
Thereby reducing the survival chances of aquatic organisms.
