How does a dense canopy of leaves help plants compete for resources?

A dense canopy of leaves allows plants to effectively capture sunlight by maximizing light interception, which is crucial for photosynthesis. This competitive advantage enables them to grow faster and outpace neighboring plants in accessing light. Additionally, a thick canopy can reduce light penetration to lower layers, limiting the growth of understory plants and reducing competition for water and nutrients. Overall, a dense canopy enhances a plant's ability to thrive in resource-limited environments.
