There are two types of environmental factors that influence organisms.


Biotic Factor:  living things that affect an organism

Example: diseases, food, trees, classmates


Abiotic Factor: nonliving things that affect an organism

Example: wind, rain, minerals in soil, temperature


Organisms are adapted to specific biotic and abiotic factors in their environment.

Example: The arctic fox is adapted with thick fur to survive in very cold temperature. (Abiotic Factor) 

The food source of the arctic fox is a small rodent called a lemming, found in the arctic circle.


An ecosystem consists of all organisms in an area that interact as well as the abiotic surroundings.
