Organisms such as blue green algae and bacteria. No double strands of DNA.
What is Monera.
100
The region of ocean that covers the continental shelf.
What is Neritic Zone
100
The zone lakeward from the littoral zone extending from the surface of the water to the approximate depth of the littoral zone.
What is the Trophogonic, Lemnetic or Pelagic Zone
100
Monomictic, dimictic and polymictic.
What are the thermal zones of lakes
100
The primary limiting factor on land.
What is moisture
200
Simple , single-celled eucaryotes such as protozoans.
What is Protista.
200
The region of ocean that is beyond the continental shelf
What is the Oceanic Zone
200
It is similar to the aphotic zone of oceans in that it is defined as the deeper zone where light can not effectively penetrate and respiration exceeds photosynthesis.
What is Trophlytic Zone
200
Some lakes may become bogs where the levels of calcium carbonate are low, humus content is high, nutrients levels are very low and the pH is low and characterized by having brown water
What are dystrophic lakes
200
Provides a much more important source of nutrients than in oceans and lakes and is a very complex ecosystem in its own right.
What is soil
300
Multicellular animals including Parazoa (sponges) and other metazoan animals.
What is Animalia
300
The edge of the sea which rises and falls with the tides
What is the Intertidal or Littoral Zone
300
It is generally the peripheral shallow zone which extends from the shoreline of a lake to the depth where plants no longer are found.
What is the Littoral Zone.
300
The upper region of a lake which is characterized by being well mixed, well illuminated and nearly isothermal.
What is the epilimnion
300
1. Boreal
2. Paleotropical (African, Indo-Malaysian and Polynesian)
3. Neotropical
4. South African
5. Australian
6. Antarctic
What are Biogeographic regions based on plants
400
Multicellular plants including vascular and nonvascular forms. Some authors place algae in this Kingdom
What is Plants.
400
The region just above the intertidal zone.
What is the Supratidal or Supralittoral Zone
400
In lakes it is the zone which extends lakeward from the littoral zone into deeper water.
What is the Sublittoral Zone?
400
At the bottom of the lake, a region which is poorly illuminated, denser and colder water where wind action has no substantial effect.
