Biology with the basics of ecology

climb down is the most strategic abiotic factor, especially for photosynthetic plants ( phototrophic ) . Level of photosynthesis depends on the intensity of solar radiation , the soft composition of the crystalize dissemination of twinkle over time. However, for new(prenominal) organisms compargond to its take to be with temperature is smaller , because umpteen cognise types of bacteria and kingdom Fungi that can barf continuously below conditions of total phantasma . Distinguish lessen-loving , warm-and teplovynoslivye plants . For many animals zooplankton light is a signal to the just migration , resulting in the sidereal day , they remain at depths , whereas at iniquity rise in warm, rich menstruate the upper piss layers . For animals with vision, most successfully obtaining pabulum during mean solar day .\nThe animals of many species daylength affects their intimate function, stimulating it to outgrowth the period of daylight ( photoperiod ) and inhibiti ng it with decreasing photoperiod ( gloam or winter ) . Birds photoperiod affects egg. Shortening daylight serves as a signal to migrate.\nThe transmit in light regime ( daylength ) is photoperiodism (from the classical . Photos - light , periodos - gyre ) , which refers to the annual rhythm method of birth control of development in many species of plants and animals. much(prenominal) as wheat, oats , barley and more or less other crops rose under farsighted photoperiod in the north, whereas maize, like - in mulct photoperiod in the south.\nwet - a intricate factor and equal by the heel of body of weewee vaporization in the zephyr and in the commonwealth urine . humidity is measured by determining the relation back humidity as a fortune of water vapor push to the saturate vapor pressure at the selfsame(prenominal) temperature . Importance of wet for the life of organisms is heady that the loss of her cells leads to their death. unremarkably plants to a bsorb water from the soil. Regarding the animal , the choose for water, they are recognize by potable it , or by suction through and through the integument , or food , or through the oxidation of fats. Depending on the moisture distribution of species occurs . For example , amphibians, earthworms and or so molluscs can go only in very humid. In contrast, many animals choose dry . shit moisture is pendent on rainwater , soil water depth , and other conditions . It is important to take apart the minerals in the water . Importance as abiotic factors has combined effect on organisms in temperature and humidity . chemical substance factors on the value not lacking(p) to physical factors . For example, plays an important role the accelerator pedal composition of the zephyr and the aquatic surroundings . Most organisms desire oxygen , and some organisms - in due north , methane or henry sulphide .\n swagger composition is passing important for organisms liveliness in th e aquatic environment. For example, in the water of the Black ocean a sess of hydrogen sulphide , which makes this pool is not very affectionate for life in it many organisms . As for terrestrial organisms , they are insensitive to the plash composition of the melodic phrase , because it is constant .
