sentences: photosynthesis means green plants convert from carbon dioxide and water and solar energy into carbohydrates and food and oxygen for themselves & photosynthesis is a kind of process ->  photosynthesis is a kind of process in which plants convert carbon dioxide and water and solar energy into carbohydrates and food ans oxygen for themselves  a plant is a kind of organism & if an organism uses a process to convert something into something else, then that organism is a source of that something else through that process ->  if a plant uses a process to convert something into something else then that plant is a source of that something else through that process  photosynthesis is a kind of process in which plants convert carbon dioxide and water and solar energy into carbohydrates and food ans oxygen for themselves & if a plant uses a process to convert something into something else then that plant is a source of that something else through that process ->  plants are a source of carbohydrates through photosynthesis  plants are a source of carbohydrates through photosynthesis & carbohydrates are made of sugars ->  plants are a source of sugar through photosynthesis  photosynthesis means green plants convert from carbon dioxide and water and solar energy into carbohydrates and food and oxygen for themselves & photosynthesis is a kind of process ->  photosynthesis is a kind of process in which plants convert carbon dioxide and water and solar energy into carbohydrates and food and oxygen for themselves  a plant is a kind of organsim & if an organism uses a process to convert something into something else, then that organism is a source of that something else through that process ->  if a plant uses a process to convert something into something else, then that plant is a source of that something else through that process  photosynthesis is a kind of process in which plants convert carbon dioxide and water and solar energy into carbohydrates and food and oxygen for themselves & if a plant uses a process to convert something into something else, then that plant is a source of that something else through that process ->  plants are a source of oxygen through photosynthesis  plants are a source of sugar through photosynthesis & plants are a source of oxygen through photosynthesis ->  plants are a source of oxygen and sugar through photosynthesis  plants are a source of oxygen and sugar through photosynthesis & a source of something produces that something -> plants produce oxygen and sugar through photosynthesis
