When huge numbers of algae grow at the surface of the water, this is called?

(a)  

Leaching of nitrates and phosphate ions from soil that has been recently fertilised into a nearby river causes algal bloom as algae can grow rapidly at the surface of the water whereas previously nitrate concentration was stopping that. This algal bloom reduces the amount of (a)   that enters the water and algae at the bottom of the river die.

Algal bloom stops algae and plants at the bottom of the river from carrying out the reaction (a)  

Increased algal death and plants at the bottom of the river results in an increase in the numbers of decomposers which use up (a)   , meaning less available for fish and other aerobic organisms, meaning they die
