| Organisms that eat only herbivores | secondary consumers or carnivores |
| Organisms that eat secondary consumers | tertiary consumers |
| Removing a phosphate group from ATP to make ADP _________ energy. | releases |
| Organisms that produce their own food are called | Autotrophs or producers |
| Organisms that have to consume food for energy are called | Heterotrophs or consumers |
| What are the reactants of cellular respiration? | oxygen and glucose |
| What are the reactants of photosynthesis? | carbon dioxide, water, and energy |
| What are the products of cellular respiration? | carbon dioxide, water, and energy |
| What are the products of photosynthesis? | oxygen and glucose |
| Photosynthesis takes place in the | chloroplast |
| Cellular respiration takes place in | mitochondria |
| 1st step of photosynthesis - requires light energy to split water into oxygen gas and hydrogen atoms. | Light-Dependent Reactions |
| 2nd step of photosynthesis - uses ATP as its source of energy to add hydrogen atoms to carbon dioxide and make glucose. | Calvin Cycle |
| The initial source of energy for most communities is | sunlight. |
| The energy released from ATP breaking down into ADP is used to perform | cellular work & life functions. |
| Organisms that break down organic matter and return nutrients to the environment. | decomposers |
| Anaerobic process that harvests energy from food to make ATP. | fermentation |
| Type of fermentation that produces lactic acid. | lactic acid fermentation |
| Type of fermentation that produces ethyl alcohol and carbon dioxide. | alcoholic fermentation |
| Involving or requiring oxygen | aerobic |
| Involving or requiring an absence of oxygen | anaerobic |
