What is chronic fatigue syndrome? Chronic fatigue syndrome (CFS) is a disorder that causes ongoing, extreme fatigue that is not explained by any known medical condition. It can affect a person's ability to perform routine, daily activities or tasks. People with CFS sleep poorly and awake unrefreshed.
Solar energy is converted into chemical energy. Photosynthesis is the process whereby plants using light energy from the sun convert carbon dioxide and water to glucose sugar and oxygen gas through a series of reactions. The overall equation for photosynthesis is. Light energy from the sun is converted into chemical energy by the production of glucose molecules. Photosynthesis is carried out in the chloroplasts of plant cells using the green pigment chlorophyll. Glucose is produced which is converted into starch. Starch is a polymer made up of repeating glucose units.
The primary source of energy for nearly all life is the Sun. The energy in sunlight is introduced into the biosphere by a process known as photosynthesis, which occurs in plants, algae and some types of bacteria. Photosynthesis can be defined as the physico-chemical process by which photosynthetic organisms use light energy to drive the synthesis of organic compounds.
