Law of Conservation of Mass and Energy in Living Things
| Term | Definition |
|---|---|
| photosynthesis | process through which producers make their own food using light energy |
| chloroplasts | cell organelle where photosynthesis occurs, filled with chlorophyll |
| chlorophyll | green pigment that absorbs sunlight to use in photosynthesis |
| reactants of photosynthesis | carbon dioxide, water, sunlight |
| products of photosynthesis | sugar (food for plant), oxygen (waste product) |
| cellular respiration | process through which producers and consumers use food to make ATP energy |
| mitochondria | cell organelle where cellular respiration occurs |
| reactants of cellular respiration | sugar, oxygen |
| products of cellular respiration | carbon dioxide, water, ATP (energy) |
| fermentation | a form of anaerobic respiration where producers can make ATP without oxygen present |
| carbon cycle | how carbon is moved from the soil, atmosphere, and living things through photosynthesis, cellular respiration, combustion, and decomposition |
| greenhouse effect | carbon dioxide and other gases in the atmosphere trap solar energy and allow earth to be warm enough to support life |
| reactants | compounds used to start a chemical reaction |
| products | compound produced in a chemical reaction |
| energy transformation in photosynthesis | light energy to chemical energy |
| energy transformation in cellular respiration | chemical energy in food to useable chemical energy as ATP |
| law of conservation of mass | mass cannot be created or destroyed |
| law of conservation of energy | energy cannot be created or destroyed |
