Photosynthesis:


     Photosynthesis, the process of plants gaining food from the Sun and the production of oxygen. Humans and other mammals need oxygen to survive. Without the process of photosynthesis, humans and all land animals will most likely die. Most of the Sun’s energy gets scattered before it hits the Earth’s surface. But, the little sunlight that hits the Earth’s surface is what starts the photosynthesis.

     Light creates colors that give energy to plants. Only the sunlight would be considered food to them. When the sunlight hits the plants, reactions occur and sugar energy is made for plants. Light that hits the earth comes in all sorts of colors from the rainbow spectrum. The colors come from the Sun’s wavelength of light. Plants will mostly absorb red and blue. They reflect the other colors such as green and yellow. This occurs because plants do not want to absorb all colors given by the sun.

     When the Sun hits Earth, it creates molecules for life and feed plants. The sunlight creates hydrogen from the light piercing Earth. Then, plants release carbon dioxide and that is then mixed with water to create oxygen. Water comes from hydrogen and oxygen mixing together. The sun hits the Earth and creates water from the oxygen that is on Earth.

     The whole photosynthetic process is created by having three main components. The three components are Sun, water, and plants. Without the three parts, there will be no oxygen for humans to breathe on. Humans need plants, trees, sunlight, and water to breathe on a planet. Other animals that live on land need these three components as well. Photosynthesis, is an important oxygen creation process that allows animals to breathe air in order to exist.
