---|---|
Metabolism | The sum total of all processes in an organism which convert energy and matter from outside sources and use that energy and matter to sustain the organism's 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 their own food |
Herbivores | Organisms that eat only plants |
Carnivores | Organisms that eat only organisms other than plants |
Omnivores | Organisms that eat both plant and other organisms |
Producers | Organisms that produce their own food |
Consumers | Organisms that eat living producers and/or other consumers for food |

Sexual reproduction | Reproduction that requires two organisms |
Inheritance | The process by which physical and biological characteristics are transmitted from the parent (or parents) to the offspring |
Mutation | An abrupt and marked change in the DNA of an organism compared to that of its parents |
