| Biotic factors/resources are living or once-living organisms in the ecosystem. These are obtained from the biosphere and are capable of reproduction. | Abiotic factors/resources refer to non-living physical and chemical elements in the ecosystem. Abiotic resources are usually obtained from the lithosphere, atmosphere, and hydrosphere. |
| Biotic factors depend on abiotic factors for survival and reproduction. | Abiotic factors are completely independent of biotic factors. |
| Examples of biotic resources include all flora and fauna. | Examples of abiotic factors include precipitation, altitude, temperature, type of soil, minerals, geographic location, humidity, wind, dissolved oxygen, turbidity, water depth, etc. |
