FRESHWATER HABITASTS

3. Freshwater habitats can be distinguished into two kinds, namely the quiet fresh water (reservoirs, marshes, ponds, pools, etc) and fresh water flowing (River).
The characteristics of freshwater habitat:
a. the main Producers are the microscopic green plants (algae and fitoplanton).
b. the Salinity is low, even lower than the protoplast.
c. low temperature variations.
d. the penetration of the Sun's light is reduced.
e. On the ecosystem of the river water flow occurs all the time.
f. climate and weather-influenced.
g. physical and biological habitat of the freshwater habitats of the sea and the
    intermediate land habitats.
Freshwater biomes is physically divided into three regional sections:
a. Regional litoral is a shallow water areas and get the sunlight to penetrate to the
    bottom. Organisms that live in the region of litoral e.g. plants its roots, worms,
    shrimp and plankton.
b. limnetik Area is an area of open water and sunlight is still able to penetrate to the
    essence. Organisms that live in the area of limnetik such as nekton, neutson and
    plankton.
c. the basic area is the profundal Region water and sunlight cannot penetrate to the bottom.

4. The Habitat of Sea Water.
    Broad habitat of sea water or accounting for around 70% of the entire surface of the Earth. High levels of salt effect to the mineral content, but each place has different levels of salt because influenced by climatic conditions and the parts of the world.
Based on the intensity of the light, the marine habitats can be classified into 3 parts:
a. the area of the sea is an area of fotik with a depth of 0-200 meters and allows sunlight
    to penetrate to the bottom.
b. the area of the sea is an area of twilight with a depth between 200 to 2000 meters.
    The sunlight was able to penetrate the depths but only at looking Dim.
c. Afotik Area is the area of the sea with a depth of over 2000 meters. Absolutely no
    sunlight can penetrate so that this area is very dark.
Based on its position of marine habitat are distinguished into four kinds:
a. Regional litoral, is the beach area or bordering land.
b. Regional neritik, is an area of shallow sea, which reaches 200 meters kedalamanya.
c. Regional batial sea area, which has a depth of 200-200 metres.
d. Regional abisal, sea area has a depth of 200 more.
Marine habitat characteristics include:
a. high salt Levels (especially in the area of tropical rainforest, and lower in the colder regions).
b. Marine Habitats with each other always associated (to be continued).
c. marine ecosystems is not affected by climate and weather.
d. ocean currents always spinning due to differences in climate and temperature, as well as the Earth's rotation.
Community on the ocean habitat consists of several types, including the following:
a. the manufacturer, including phytoplankton and algae (in tropical regions), green
    algae, red algae, blonde algae living as benthos or perifiton.
b. This bacteria, amonifikasi and bacterial fermentation.
c. Consumers, covers the types of animals from different phyla (from the lowest to the mammals).
d. Zooplankton, such as temporary and permanent plankton plankton.
