ecology factors

The factors that affect distribution and abundance of an organism.

Abundance and Distribution

The spread of is movement individuals from the origin or from the center population density high. The spread of will give a contribution for distributing global organisms. Factors that affects distribution and abundance organisms there are two types of factors biotic and factors abiotic.

1.      Factors biotic or factors lives, all organisms that is part of the neighborhood of an individual. Factors biotic of a an organism that feeds on may limit distribution an organism that edible. Besides pemangsaan and herbivore , existence or a lack of food , parasitic , pathogen , and an organism competitors can act as parapet biotic for distributing species. The biotic environment includes genes, cells, organisms, members of the same species (conspecifics) and other species that share a habitat.

2.      Factors abiotic:

a.     Temperature:  the environmental temperature a factor that was important in the distribution of organisms as its effect on the biological processes .The cells may be broke out when the who were conceived frozen ( at temperatures below 00c ) and proteins in most organisms denatured at temperatures above 450c . Most organisms function best in the range of specific the environmental temperature .The temperature outside the range can force some animals spend energy to regulate internal temperature.

b.    water:  variation drastic in the availability of water of habitat-habitat different is a other important factor in distribution species. Species that live in coastal or in wetlands pairs of can terdesikasi ( dries as tidal. Organisms land to combat the threat of desikasi continuous , and distribution species of terrestrial reflecting the capability obtain and observe the  water.

c.   Salinitation : most aquatic organisms living limited in watery habitats fresh or salted watery because it has a limited ability to osmoregulation.

d.   Sunlight: rays the sun absorbed by photosynthetic organisms can provide energy , and sunlight too little may limit distribution species fotositetic. In the environment aquatic , every meters the depth of water selectively absorbed about 45 % the red rays and around 2 % blue rays through the water. As a result , most fotositetis to environment aquatic happened relative at near the surface.

e.   Rocks and land: ph composition land, and physical structure of rocks and land limit distribution plants and you as distribution of animals plant eating. Ph land and water can restrict distribution of organisms directly through the acid or bases extreme indirectly via solubility toxin and nutrient.

f.   Climate:  four factors abiotic; temperature , rainfall , sunlight , and wind is main komponen-komponen climate. The climate , especially the temperature and availability of water had a profound impact on distribution of land. The this climate there are two kinds of the micro climate and climate macro.

g.    The global climate: the effects of global warming against the atmosphere, land and water set temperature variations, the air cycle, and evaporation water in charge of variation drastic according to the climate.

 

Refleksi diri

In the first meeting ecology I’am studied about the meaning of ecology. So I can conclude that ecology is the science who study about distribution and abundance of organism. In this meeting I’am so interest with this topic. Because this is the first meeting so we not study full, but only introduction what is ecology and how study ecology. Beside that, we also prepare group for practicum and KKL.

The second meeting, we have a assignment from Mr. Hadi suwono to resume about The factors that affect distribution and abundance of an organism, and make a blog. This blog we use as e-portofolio.
