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

Nutreint Cycles
