Biotic (living) factors:
* Trees: The dominant plants in a forest ecosystem, providing habitat, food, and oxygen.
* Deer: Herbivores that graze on plants, contributing to the forest's biodiversity and nutrient cycling.
Abiotic (non-living) factors:
* Sunlight: The primary energy source for the forest ecosystem, driving photosynthesis.
* Soil: The foundation of the forest, providing nutrients and water to plants, and supporting a diverse range of microorganisms.
