Taller trees have a canopy arrangement of leaves where the upper leaves tend to be smaller than the ones below them. How does this arrangement of leaves benefit the plant?

Answers

Answer 1
Answer: This is because the leaves below need more light since they are less exposed to the sun. They are longer and can absorb more and photosynthesize more. The upper ones need less light and less materials since they are more exposed to the light.
