'Summary: Biotic relationships of organisms'

'\n\nThe develop twist of cosmoss characterizes the natural tally represented in it develops and the proportionality of their numbers pool or biomass. This ratio is usually called the eld scattering ( distribution of population by grow base ) or age range of the population.\n get on range associated with the strong point of mortality of organisms. In addition, it also depends on the magnitude of fullness , as hardened by the cherish of the last bedding material . Population age structure may change low the influence of outside(a) factors , since they control the processes and fertility and mortality.\nAccording to the age range estimated populations ability to self and its resilience , the harder the age spectrum , the more than stable counter of the population.\nMnogovozrastnye populations are overmuch less minute with respect to the factors that gestate an impact on certain population subgroups (eg, juveniles ) . Indeed, the number of juveniles is a relati vely thin proportion of the total population .'
