Detailed explanation-1: -Without the sun there would be no vegetation on earth, because every plant needs light to live and grow. The sun even enables them to generate oxygen by means of photosynthesis, which humans and animals need to breathe. The earth’s position in the solar system is optimal for the development of life.
Detailed explanation-2: -Without the Sun, Earth’s land, water, and air would all be frozen solid! Life on Earth would cease to exist. That’s because almost all living things rely on the steady light and heat of the Sun. The Sun’s heat makes liquid water on our planet possible.
Detailed explanation-3: -There are some organisms that have been discovered that are able to survive without using the sun’s energy. They are types of bacteria called extremophiles, and are found in extreme environments where most organisms would die.
Detailed explanation-4: -A person can live without sunlight, though it’s not recommended. Medical experts suggest 10-15 minutes of sun exposure each day though this varies on geographical location. Deficiency can lead to a lack of Vitamin D, contributing to mood disorders, weaker bones and trouble sleeping.
