| Question | Answer |
| What is life? | 1. All life forms contain deoxyribonucleic acid, which is called DNA. 2. All life forms have a method by which they extract energy from their surroundings and convert it into energy that sustains them. 3. All life forms can sense changes in their surroundings and convert it into energy that sustains them. 4. All life forms reproduce |
| Metabolism | The sum total of all processes in an organism which convert energy and matter from outside sources and use that energy and matter it to sustain the organisms life functions. |
| Anabolism | The sum total of all processes in an organism which use energy and simple chemical building blocks to produce large chemicals and structures necessary for life. |
| Catabolism | The sum total of all processes in an organism which break down chemicals to produce energy and simple chemical building blocks. |
| Photosynthesis | The process by which green plants and some other organisms use the energy of sunlight and simple chemicals to produce its own food. |
| Herbivores | Organisms that eat only plants. |
| Carnivores | Organisms that eat only organisms other than plants. |
| Omnivores | Organisms that eat both plants and other organisms. |
| Producers | Organisms that produce their own food |
| Consumers | Organisms that eat living producers and/or other consumers for food. |
| Decomposers | Organisms that break down the dead remains of other organisms. |
| Autotrophs | Organisms that are able to make their own food. |
