Open shore water surface layer away from the shoreArea where the most photosynthesis occursProducers supply most of food and oxygen supporting

the consumers

Deep open waterFish adapt to darker and cooler waterToo dark for photosynthesis

RIGGERS

humans need to concentrate on limiting their impacts on freshwater ecosystems

each fresh water zone is very unique and diverse in its own way
