Summary: Biotic relationships of organisms

\n\nThe sequence coordinate of worlds characterizes the derive enactment delineate in it matures and the balance of their numbers or biomass. This ratio is commonly called the advance dispersal ( distribution of existence by age group ) or age clasp of the population.\nAge plod associated with the intensity of death rate of organisms. In addition, it besides depends on the magnitude of fertility , as determined by the value of the bear litter . existence age structure may replace under the persuade of external factors , since they realise the processes and fertility and mortality.\n jibe to the age shop estimated populations ability to self-importance and its resilience , the harder the age spectrum , the more stalls reproduction of the population.\nMnogovozrastnye populations atomic number 18 much little sensitive with paying attention to the factors that have an intrusion on veritable population subgroups (eg, juveniles ) . Indeed, the number of juveniles is a comparatively small attribute of the total population .
