Mercury can enter aquatic ecosystems by
combustion of coal releases particulates with mercury attached that can be deposited in downwind aquatic ecosystems by particulates or precipitation, coal ash ponds can overflow which releases mercury into nearby surface water
The loss of wetlands and mangroves can lead to a decrease in this type of biodiversity, which refers to the variety of different species in an ecosystem.
What is species biodiversity?
What usually causes thermal pollution?
Power plants releasing warm water into local bodies of water.
