Plants take in – or ‘fix’ – carbon dioxide from the atmosphere during photosynthesis. Some of the carbon is used for plant growth, and some of it is used in respiration, where the plant breaks down sugars to get energy. Related Images:
When they photosynthesise, plants use sunlight to break apart water into hydrogen and oxygen, and then combine the resulting hydrogen with carbon dioxide from the air to create carbohydrates. Related Images:
