Biotic Factor

Important Abiotic Factors

- Light Availablitly - Temperature - Availablilty to Water - Compostion of soil and nutrient/mineral availibilty - Tides - Salt levels.

Examples of Biotic Factor

- Predator prey relationships - Disease causing bacteria - Poisonous plants - a huge tree that has fallen across a path - a dead moose that is found in bog
