A. Nutrients
B. Frost
C. Oxygen
D. Sunlight
✅ The correct answer is option D.
Due to the older age and species diversity of the temperate forest ecosystems, many grasses and lower lying shrubs have difficulty growing to the breadth of the canopy composed of the taller trees. As a result, little sunlight actually reaches the forest floor, which serves as its own limiting factor.
