| Conservation of Mass | The principle that mass cannot be created or destroyed; also conservation of matter. |
| Consumer | An organism that feeds on other organisms for food. |
| Electricity | The physical phenomena arising from the behavior of electrons and protons that is caused by the attraction of particles with opposite charges and the repulsion of particles with the same charge. |
| Energy | The capacity to do work. |
