- The climate, amount of precipitation, and soil type are abiotic factors—the nonliving elements—that define a biome.
- The plant and animal kingdoms are examples of biotic factors, which are the living elements.
- For plants to grow, they need carbon dioxide, water, and sunlight.

- Abiotic interactions, on a broader level, refer to climatic and seasonal cycles.
