The oxygen-rich surface water blends with the deeper, depleted water. The dissolved oxygen concentration in the mix can be too low to support life in the pond. Both fish and plankton can die from low dissolved oxygen following a turnover. Thus, turnover can happen if a cold rain and wind cools the surface water.
Answer:
The protein that are intake through foods are broken down in the body and is converted into nitrogenous waste products which are eliminated from the body through the process of excretion.
Explanation:
Ammonotelic-Those organisms that excrete nitrogenous waste products in the form of ammonia from the body throuh the process of excretion is called as ammonotelic animals.Ammonia is more soluble in water.
Ex- Bony fish, Octopus, Sepia etc.
Ureotelic-Those organisms that excrete nitrogenous waste products in the form of Urea from the body through the process of excretion is called as Ureotelic organisms.Urea is soluble in water.
Ex- Human.
Uricotelic-Those organisms that excrete nitrogenous waste products in the form of Uric acid from the body through the process of excretion is called as uricotelic organisms.Uric acid is insoluble in water.
Ex- Reptiles, birds etc.
