Autotrophs:
-Phytoplankton
-Grassy Pondweed (found in North America)
-Cat Tails (wetlands)
-Watercress (cool water, springs and brooks)
-Bacteria
Hetertrophs:
-Zooplankton
-Carp or freshwater fish
-Wetland birds
-Insects
-Tadpoles
Decomposers:
-Fungi
-Bacteria
-Earth worms
-Snails
-Bottom feeders
All decompose fresh water organic materials and apex predators in close proximity to freshwater.
Keystone Species:
-Salmon:
Salmon are a freshwater keystone species because they are directly fed on by bears and other mammals that effect the food chain on land.
-Salamanders:
Salamanders are another keystone species because they directly impact the flora and fauna found near bodies of freshwater.
