Autotrophs - organisms that use light or chemical energy and inorganic molecules (carbon dioxide and water) to synthesise complex organic molecules
Herterotrophs - organisms that ingest and digest complex organic molecules, releasing the chemical potential energy stored in them
Oxygen first appeared in the atmosphere after being released from photosynthesis - photosynthesis appeared before respiration
Photosynthesis takes place in organelle called chloroplasts
