Asexual reproduction | Production that does not involve the union of sex cells and in which one par- ent produces offspring that are genetically identical to the parent |
Producer | An organism that can make its own food by using energy from its surroundings |

Sexual reproduction | Reproduction in which the sex cells from two parents unite to produce offspring that share traits from both parents |
