Some communities have banned detergents containing high levels of phosphates because: Phosphates kill algae and disrupt normal food webs in lakes Phosphates cause chemical reactions that increase the temperature of the water Phosphates are not effective cleaners Excessive phosphates in lakes may begin a process that causes fish to suffocate and die

Answer:Excessive phosphates in lakes may begin a process that causes fish to suffocate and die

Explanation: when detergents are washed into water bodies, excessive phosphate causes eutrophication. eutrophication is the excessive growth of algae due to plenty nutrients in the water body. when these algae decay, they use up oxygen and causes inadequate oxygen for fishes and other marine organisms.

It could lead to death of these fishes and in the process of decay, they use up more oxygen causing more oxygen shortage in the water
