The major differences between biotic and abiotic factors are,
| Sl. No. | Biotic factors | Abiotic factors |
| 1 | The living components are termed as biotic factors. | Physical or nonliving factors that shape ecosystems are called abiotic factors. |
| 2 | In ecosystem, these factors influence the other organisms directly. | In ecosystem, these factors influence the organisms indirectly. |
| 3 | These include the entire living things with which an organism might interact (Ecological community). | These include the entire nonliving things with which an organism might interact (Ecological community). |
| 4 | For example: Producers, which include plants. Consumers, which include animals (depend on producers for energy). Decomposers, which include bacteria and fungi (They decompose dead organic matter into simple substances). | For example: the climate of an area includes abiotic factors such as, temperature, precipitation, and humidity. Other abiotic factors are wind, nutrient availability, soil type, sunlight. |
Biotic and abiotic factors determine the survival and growth of an organism and the productivity of the ecosystem in which the organism lives.
