Explanation:

You may have noticed that vegetables change color in the fall. This change is perceived in some species more quickly than in others. The three species that change color the latest in autumn are trees, flowers and grass.

This color change occurs because, the vegetables are composed of particles called chlorophyll, which are the particles that promote the color that we see in the leaves, flowers and fruits, in addition, these particles are the main responsible for the process of photosynthesis.

As in the autumn the incidence of sunlight is reduced, photosynthesis is performed in a weaker way. With that, the plants understand that they don't need that much chlorophyll and end up discarding this molecule. With that, the vegetables start to lose their usual colors and new colors appear.
