| A | B |
| process that captures light energy | photosynthesis |
| bacteria at ocean floor use to make food | chemosynthesis |
| trophic level with most energy available | 1st trophic level |
| photosynthesis & chemosynthesis | processes that producers do |
| energy molecule made during respiration | ATP |
| waste products made during respiration | carbon dioxide & water |
| molecules made during photosynthesis | glucose (sugar) & oxygen |
| carbon dioxide & water | starting reactants of photosynthesis |
| glucose & oxygen | starting reactants of respiration |
| anaerobic respiration | makes a small amount of ATP |
| no oxygen required; makes ATP | anaerobic respiration |
| aerobic respiration | makes the most ATP possible |
| oxygen required; makes ATP | aerobic respiration |
| where cell respiration happens | mitochondria |
| where photosynthesis happens | chloroplasts |
| chloroplasts | capture/convert light energy to chemical |
| mitochondria | release energy stored in sugar molecules |
| lost at each trophic level | energy |
| energy | not recycled in ecosystems |
| type of energy captured by chloroplasts | light |
