Question

Do the Leafs on a plant compete with other leaves on the same plant for sunlight?

Answer 1

Not always, but some times may happen because the top leaves may shade the bottom leaves.

Answer 2

No. Leaves of the plants receive the same amount of sunlight, unless they are covered with other leaves, or if they are in the bottom. Competition happens only if there is a limited amount of supply for the population. In the case of leaves, there is always sunlight available, it only depends where they are placed.
