207105385 | Homeostasis | The internal balance an organism makes to adjust to the environmental changes | |
207105386 | Metabolism | The sum of all chemical reactions used by an organism to obtain and use the energy found in food | |
207105387 | Producer | Organisms that convert solar energy to chemical energy. These can be plants and other organisms that use photosynthesis | |
207105388 | Consumer | Organisms that get their energy by eating other organisms | |
207105389 | Decomposer | Organisms that get their energy by breaking down dead and decaying organisms | |
207105390 | Digestion | 1st part of metabolism; The breaking down of complex food molecules into smaller more useful pieces | |
207105391 | Respiration | 2nd part of metabolism; mixing of food with oxygen to release the energy in it. | |
207105392 | Synthesis | 3rd step of metabolism; putting molecules together for growth and repair | |
207105393 | Excretion | Final part of metabolism; removal of waste products from an organism | |
207105394 | Environment | All the surroundings of an organism; includes living and non-living parts | |
207105395 | Biotic | Living parts of the environment - other organisms | |
207105396 | Abiotic | Non-living part of the environment - air, water, soil, climate | |
207105397 | Stimulus | A change in the environment that can cause an organism to change its behavior; anything that causes a reaction | |
207105398 | Response | A change in behavior due to a change in the environment | |
207105399 | Adaptation | Any inherited characteristic or trait an organism has that makes it better able to survive in its surroundings | |
207105400 | Asexual reproduction | Requires only 1 cell (parent); produces offspring identical to parent; aka cloning | |
207105401 | Sexual reproduction | Requires two cells (parents); produces unique individuals which possess traits from both parents | |
207105402 | Heredity | Passing of traits from parent to offspring | |
207105403 | Growth | A change in size over the life span of an organism; in multicelled organisms requires more cells; often occurs at same time as development | |
207105404 | Development | All the changes an organism undergoes as it grows and matures; A change in form | |
207105405 | Life Span | The natural length of time an organism will live. This varies from species to species. Some species live for 3,000 years, some for 24 hours | |
207105406 | Organism | Any living thing; made up of at least 1 cell and possessing all other characteristics of living things | |
207105407 | Cell | Membrane bound structure; the smallest unit of life in which life processes are carried out |
