    The abundance of organisms in an ecosystem is dependent upon biotic (living) and abiotic (non-living) factors.

    The abundance is the number of organisms in an ecosystem and their distribution is affected by abiotic factors.

    They include:Light intensity , temperature , moisture levels , soil pH content , soil mineral content , carbon dioxide levels for plants , wind intensity and direction , oxygen levels for aquatic animals  

    Biotic factors : New predators , availability of foood , new pathogens , out-competition -The introduction of a new species into an ecosystem can result in it out-competing another native species.
