Freshwater | Biology | Ecology
This video on Aquatic Biomes begins by looking at the characteristics common to all aquatic environments. The program then examines the littoral, limnetic and profundal zones of freshwater lakes, the seasonal cycling of O2 and nutrients, and the difference between oligotrophic and eutrophic lakes before observing how life changes along the course of rivers and explaining the ecological importance of wetlands. The photic, aphotic, and benthic ocean zones are then described and marine habitats such as tide pools, kelp forests, coral reefs, and vent communities explored.
Wetlands | Biology | Ecology
A Wetland is described by the plant species that live in it. If an area is wet enough for long enough to support a majority of plants that are adapted to wet conditions then you have a wetland
The tides are generated by the gravitational forces between the Moon, the Sun and Earth. The Intertidal zone is the coastal area between the high tide mark and the low tide mark. Not a huge area maybe, but for the organisms that live here it mean putting up with some serious physical and biological stresses.
