Organisms with similar needs may contend with each other for resources, including food, space, drinking water, air, and shelter. In virtually any particular environment, the expansion and survival of organisms rely upon the physical conditions including light level, temperature range, nutrient availability, ground type, and pH. Physical or non-living factors such as these which affect living things are called abiotic factors. Living factors which impact living things are called biotic factors.
Examples of abiotic factors include,
- Water
- Fire
- Ice
- Soil
- Temperature
- Sunlight
- Lightning
Biotic factors are living factors within an environment.
