<human>:  What is the difference between photosynthesis and respiration?
<bot>: Photosynthesis is the process by which plants, algae, and some bacteria convert the light energy from the sun into chemical energy stored in the form of sugars. This is used to produce carbohydrates which are the building blocks of life. Respiration on the other hand is the process by which organisms use the sugars that have been produced through photosynthesis to produce energy. During respiration, the glucose breaks down and releases energy in the form of ATP molecules that is used by the organism for growth and movement.
