The image shows a wooden plaque with Chinese text written on it. The text is written in both English and Chinese characters. The plaque appears to be made of wood and is mounted on a wooden surface. The background is blurred, but it seems to be an outdoor setting with trees and foliage visible.

The text on the plaque is in Chinese and translates to "The upper reaches of a forest canopy will receive ample sunlight, and will block sunlight from reaching the leaves located in the lower levels of the forest. In response, certain plants alter their leaf shape and size or arrange their leaves in a special way to maximize the sunlight. The upper leaves of an Indian rubber tree, for example, are smaller than the leaves near the base of the tree. Another plant species, the upper leaves have developed a different strategy for maximizing sun exposure. The lower leaves of this plant have many perforations, which allow more sunlight to reach the top of the canopy.
