They are metals. Metals are the most common.
Water itself does not live. Water does not need sustenance of any sort to continue to function and it does not pass on any sort of DNA to any build a future generation so it is not biotic.
Answer:
There are no options to this question, however, the answer is:
TURBIDITY
Explanation:
Algal bloom is a term used to describe the excessive and rapid growth of algae species on a water surface. It is caused by the pollution of a water body with nutrients, in a process called EUTROPHICATION.
Asides the low oxygen effect of this algal blooming on a water body, it can also form a cloudiness on the surface of the water body. This cloudiness causes the water to be unclear in a process that is called TURBIDITY. In other words, the water that is affected by algal bloom is said to be "TURBID" and can reduce the penetration of sunlight.
