| The term _______________ describes that in a species of organisms, there are different forms of a given trait | variation |
| In order to survive, individuals have to fight for limited resources | competition |
| The individuals that survive pass their genes down to their offspring, giving that population a better chance of survival | heredity |
| Changes in the organism's ______________ can change the selection process, causing individuals that were once successful to be removed from the population | environment |
