Sunlight is one of the two most important climatic factors for ecosystems, according to experts from the University of Illinois Extension. Exposure to sunlight also helps humans synthesize vitamin D, which helps the musc... More »

Direct sunlight reaches the Earth's surface when there is no cloud cover between the sun and the Earth, while cloud cover causes indirect sunlight to reach the surface. In gardening, sunlight falling directly on the plan... More »

The sun benefits the Earth in several ways, including giving the light animals see with or the energy needed to produce artificial light, the heat that makes life on Earth possible, and energy for plants to make food thr... More »

Plants produce oxygen as a byproduct of photosynthesis, the process that plants and other organisms use to create usable energy. Photosynthesis consists of carbon dioxide and water reacting in the presence of energy from... More »

The balanced equation for photosynthesis is: 6CO2 + 6H2O + sunlight energy = C6H12O6 + 6O2 Photosynthesis can be represented using a chemical equation: Carbon dioxide + water + light energy gives a carbohydrate + oxygen. More »

Plants make their own food through a process known as photosynthesis, which involves creating energy from sunlight, water, carbon dioxide and other nutrients. The substance in plants that makes the energy is known as chl... More »
