What are some abiotic & biotic factors that affect a population?
- 1 month ago
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.

Oh who knows.
Presence and amount of liquid water
Water quality (salinity, pH, other dissolved stuff - nitrates & phosphates, iron, ...)
Partial pressure of oxygen gas
What lives there now
What has died and enriched the soil or water
What has died and provides nesting spots / living area
What has died and contaminates the area for some while enriching it for others
