Abiotic factors made up from inanimate nature division : climatic edaphic topographic

A solar radiation. Life on Earth affects : an ultravialet radiation a visible light an infrared radiation

A light regime affects : a bird migration a reproduction a flowering of plants an orientation of insects and birds The findings are used in plant cultivation and animal husbandry.

According to their light demands organisms are divided into: stenophotic euryphotic heliophobe

Heat affects the rate of biochemical reactions

Plants Adaptation to increased temperature transpiration a reflection of the shiny leaves Adaptation to low temperature trichomes a reduction of the water content a leaf fall

Cold-blooded animals a temperature affects: a development a number of generations a colouring adaptation to cold adaptation to a high temperature

Warm-blooded animals a temperature affects: a migration a food intake a water intake a colouring behavior adaptation to cold adaptation to a high temperature

Air physical properties : pressure convections density chemical properties : composition (carbon dioxide content, oxygen, nitrogen, etc.)

Water A water intake animals: food, drinking, metabolic way plants: roots, shoots

Plant division according to water requirements. water – hydrophyte hydrophilic – hygrophyte medium requirements – mezophyte xerophilic - xerophyte

Plant adaptation to the reduced amount of water long roots hair strong cuticle storage organs reduction of leaves adjustment of metabolism

Adaptation of animals to the increased amount of water greater energy output hydrophobic surface of the body reduced concentration of body fluids

Adaptation of animals to reduced amount of water reduction of sweat glands light coloration of the body impervious surface of the body concentrated and dried feaces

Minerals macro-elements micro-elements biogenic elements

Soil origins – erosion of rocks and activity of organisms components: solid liquid gaseous edaphon – a set of all organisms living in the soil (fytoedaphon, zooedaphon)
