In contrast to natural biogeocenoses, in cultured people, at their own discretion, they create a certain species composition, control the habitat conditions of species, their number, density and types of interaction between species. By creating favorable conditions for a cultivated species, a person suppresses other species that are unnecessary to him (weeds, phytotrophic population).
The change of cultural biogeocenosis also occurs at the will of a person. Only the complexes of soil inhabitants remain sufficiently stable when changing agrocenoses.
Agrobiocenoses, or field communities, are the most widespread cultural ecosystems.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
