In Ecosystems. Organisms tend to get phosphorus from their local ecosystem. An  organism can also get nitrogen from its local ecosystem. Nitrogen  is added to the organism's local ecosyste â¦ m by bacteria from the  air.
These living organisms largely depend on the abiotic factors of the ecosystem. The small biotic unit of an ecosystem is species. The success or the failure of a species depends on the adaptations of that species, competition and the resources available in the ecosystem.
