Ecology
Marine ecosystems
The major zones in marine ecosystems are littoral, neritic, pelagic and benthic.
The littoral zone is the shoreline between land and the open sea. It is subjected to the physical violence of waves, tides and t o fluctuations, sometimes extreme of temperature, moisture and light intensity.
Freshwater ecosystem
These ecosystems are characterized as having running water (lotic) or still water (lentic)
Lotic ecosystem includes fresh water streams (springs, rivulets etc) and river trend over their course from being narrow, shallow and relatively rapid to increasingly broad deep and slow moving.
