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

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

Bottom of the lake Inhabited by fish that swim from zone to zone Mostly decomposers and detritus feeders

Impacts-
damming
transportation of invasive species by boat
transportation by motor vehicles
HUMAN IMPACTS ON FRESHWATER

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
