| Aspect | Biotic Factors | Abiotic Factors |
| Definition | · Living components of an ecosystem, including all organisms such as plants, animals, microorganisms and their interactions. | · Non-living components of an ecosystem, such as temperature, water, minerals and sunlight. |
| Origin | · Arise from living organisms and their activities within the ecosystem. | · Originate from the physical and chemical components of the environment. |
| Dependency | · Interdependent on biotic factors within the ecosystem. | · Not dependent |
| Examples | · Plants · Animals · Bacteria · Fung · Predators · Prey · Decomposers · Symbiotic relationships | · Temperature · Sunlight · Air · Water · Soil · Minerals · PH levels · Humidity · Topography |
| Roles | · Producers · Consumers · Decomposers · Primary, secondary and tertiary trophic levels. | · Influence the availability of resources · Limit the distribution of species · Affect the behavior and physiology of organisms |
| Response to disturbances | · Can respond dynamically to ecological disturbances, such as the introduction of invasive species or overgrazing. | · Often change slowly over time in response to natural geological and climatic processes. |
| Influence on ecosystem | · Directly influence the structure and functioning of ecosystems, as they form the food web and ecological relationships. | · Set the physical and chemical boundaries that shape ecosystems and determine which organisms can thrive within them. |
