Why are forest floor plants so small?

Forest floor plants are generally small due to several factors, including limited sunlight penetration, nutrient availability, and competition for resources. The dense canopy of trees above blocks much of the sunlight, creating a shaded environment where only shade-tolerant species thrive. Additionally, the forest floor often has lower nutrient levels compared to other areas, which can restrict growth. As a result, these plants have adapted to grow close to the ground, maximizing their chances of survival in a challenging ecosystem.
