They breath it in and give out oxygen.
so that they can live and their waste is oxygen so we can breath
carbondioxide.
carbondioxide
for new plants,oxygen,and carbondioxide.
Plants produce Oxygen and Carbondioxide so the plants have to made out of energy
plants give us oxygen and take carbondioxide
carbondioxide
because plants breathe in carbondioxide and breathe out oxygen which animals and human breathe in if there is no carbondioxide there will be no plants ,no animalsand no humans which means no life on earth.
Plants give out oxygen which we take in and then we give out carbon dioxide which the plants take in
CO2 or CarbonDiOxide
carbondioxide+sunlight+water=oxygen+glucose
Plants need water in order to perform photosynthesis. Photosynthesis = Water + Carbondioxide+Light -----> Oxygen + Carbohydrate Plants need to breakdown H2O molcules in order to make ATP and carry out cellular funtions. Plants need water for similar reasons that people do....except that people don't carry out photosynthesis.
