Explanation:
Effects of visible and ultraviolet light
Life could not exist on Earth without light from the Sun. Plants utilize the energy of the Sun’s rays in the process of photosynthesis to produce carbohydrates and proteins, which serve as basic organic sources of food and energy for animals. Light has a powerful regulating influence on many biologic systems. Most of the strong ultraviolet rays of the Sun, which are hazardous, are effectively absorbed by the upper atmosphere. At high altitudes and near the Equator, the ultraviolet intensity is greater than at sea level or at northern latitudes.
