Example input
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek phōs (φῶς), "light", and synthesis (σύνθεσις), "putting together". Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.
Example output
Photosynthesis is a process used by plants and other organisms to turn light into food. Plants use light from the Sun, carbon dioxide and water to make sugar. This sugar gives the plant energy so they can grow and do other things like make flowers and fruit. The process of photosynthesis also helps keep the air around us healthy and full of oxygen, which helps us breathe.
