| paradigm | theories that are extensively documented and are therefore held with a very high degree of confidence and explain a large number of interrelated aspects of the natural world |
| physical environment | the nonliving factors in an environment |
| positive feedback mechanism | mechanisms that enhance or drive change in a system |
| renewable resource | a resource that can be replenished over a relatively short period of time |
