Environment Factors

 Definition

Ecology is the scientific analysis and study of interactions among organisms and their environment.

Ecology is the study of the distribution and abundance of organisms, the interaction between organisms, the interaction between organisms and their environments, and structure and function of ecosystems.

2.      Ecology and Environmental Issues

Use a lot of  phosphate in agriculture can makes promote the growth algae on lakes when phosphate flow in water.

1.      Biotic Factors

Biotic factors can boundary distribution of spesies for example an experiment by W.J.Fletcher from University of Sydney. He has done experiment  to know development of seaweed in the urchins and limpet areas compared with seaweed in the area without urchins and limpet. In area without urchins and limpet showed the development of seaweed significantly. It tell us that an organisms (predator) can influence distribution of another organisms.

2.      Abiotic Factors

a.      Temperature = can influence biology system in organism.

b.      Water = Influence distribution species. Organism have ability to save water in it body to food reserve.

c.       Salinity = Influence balance water in organisms body  throught osmosis.

d.    Sunshine = Sunshine can boundary distribution of species photosinthetic and organism have living around.

e.       Rock and Soil = Boundary distribution of plant and distribution herbivore.

3.      Climate

Divided 2 are :

a.       Macro climate à Global level, regional, and local.

b.      Micro climate à like to organisms community have living in under tree crash.

Climate consist wind, rain, temperature, sunshine.

• ·  Latitudinal Variation in Sunlight Intensity

Earth's curved shape causes latitudinal variation in the intensity of sunlight    (Campbell, 2008).

• Seasonal Variation in Sunlight Intensity

Winter --> spring --> summer --> autumn

• ·         Global Air Circulation and Precipitation Patterns 

                 Vaporation --> wet air masses to rise (blue arrows) --> flow toward the poles --> release water --> The high-altitude air masses, now dry, descend (brown arrows) --> toward earth à absorbing moisture from the land à creating an arid climate.
