1.
Aquatic Life Zones: Pretty self explanatory, it's just places (or biomes) where the aquatic life dwell.
2.
Benthos: Organisms that live attached to or near the ocean floor
3.
Coastal Zone: The warm, nutrient-rich, shallow water that extends from the high-tide mark on land to the gently sloping, shallow ledge of the continental shelf
4.
Euphotic Zone: Upper layer of a body of water through which sunlight can penetrate and support photosynthesis.
5.
Eutrophic Lake: Lake with a large or excessive supply of plant nutrients, mostly nitrates and phosphates.
6.
Inland Wetland: Land away from the coast, such as a swamp, marsh, or bog, that is covered all or part of the time with fresh water.
7.
Intertidal Zone: The portion of the shoreline that lies between the high and low tide lines
8.
Limnetic Zone: The area in a freshwater habitat that is away from the shore but still close to the surface
9.
Littoral Zone: A shallow zone in a freshwater habitat where light reaches the bottom and nurtures plants
10.
Mesotrophic Lake: A lake whose nutrient levels often fall somewhere in between the two extremes.
11.
Nekton: All organisms that swim actively in open water, independent of currents
12.
Oligotrophic Lake: Aquatic environment (usually a lake) that contains scarce amounts of nutrients and organic matter
13.
Open Sea: The vast volume of the ocean that lies beyond the continental shelf
14.
Turbidity: Muddiness created by stirring up sediment or having foreign particles suspended (High turbidity, dirty water. Low turbidity, clean water).
