Ecological factors which affect dynamic change in a population or species in a given ecology or environment are usually divided into two groups: abiotic and biotic. The first group which is called abiotic factors are geological, geographical, hydrological and climatological parameters. But there are some specific abiotic factors and they include: water which is an essential element of life; air which provides oxygen, nitrogen, and carbon dioxide to living species and allows the dissemination of pollen and spores ; soil, at the same time source of nutriment and physical support ; soil pH, salinity, nitrogen and phosphorus content, ability to retain water, and density are all influential ; temperature which should not exceed certain extremes, even if tolerance to heat is significant for some species ; light which provides energy to the ecosystem through photosynthesis. All the living organisms that inhabit an environment create another important group of factors which is called biotic. They are, in entirety, anything that affects a living organism that is itself alive. Such things include animals which consume the organism in question, or the food that the organism consumes. Biotic factors are the living components of an organism environment, such as predators and prey. As a result the amount of these factors is a complex system and it influences on the environment and creates particular conditions for normal life on our planet.
