| metabolism | the total of all chemical reactions in an organism |
| cellular respiration | chemical reactions occur that break down food molecules into simpler substances and release their stored energy |
| fermentation | when cells do not have enough oxygen for cellular respiration |
| photosynthesis | producers use light energy and make sugars, which can be used as food |
| enzyme | cause chemical reactions, does not change, reusable |
| producer | organism that makes their own food |
| consumer | organism that cannot make their own food |
| chlorophyll | green pigment, capture light energy, found in chloroplasts |
| raw materials | carbon dioxide, water |
| photosynthesis products | sugar, oxygen |
| respiration | chemical reaction to break down food into simpler substances and release energy |
