Final answer:
Larger overall leaf size helps a plant better compete for sunlight by providing a larger surface area for capturing sunlight.
Step-by-step explanation:
The feature that would help a plant better compete for sunlight is larger overall leaf size.
Plants rely on their leaves to collect sunlight and make food through photosynthesis. Larger overall leaf size allows the plant to have a larger surface area for capturing sunlight, giving them an advantage in competing for sunlight with other plants in the same environment.
For example, plants growing in tropical rainforests have larger leaves with a larger surface area to maximize their chances of collecting sunlight in the dense canopy.
