Biotic factors can be presence of food, pathogen, or a predator.
Abiotic factors can be physical or chemical factors in the environment like PH of water or soil, temperature, speed of wind or current, availability of minerals in the soil, sun light and may more.


The presence of food, and the preferred abiotic factors by the species lead to the establishment and the growth of the population of this species in the area.
The presence of predators, diseases and unsuitable abiotic factors lead to the control of the size of population and could lead to a decrease of it due to high mortality rate or migration.
