| 203460451 | Ecosystem | All the organisms in a given area, along with the nonliving (abiotic) factors with which they interact; a biological community and its physical environment | |
| 203460452 | Community | An assemblage of all the organisms living together and potentially interacting in a particular area | |
| 203460453 | Population | A group of interacting individuals belonging to ones species and living in the same geographic area | |
| 203460454 | Organism | An individual living thing, such as a bacterium, fungus, protist, plant or animal | |

| 203460459 | Organelle | A structure with a specialized function within a cell | |
| 203460460 | Molecule | a group of two or more atoms held together by covalent bonds | |
| 203460461 | Atom | The smallest unit of matter that retains the properties of an element | |
| 203460462 | Producer | An organism that makes organic food molecules from carbon dioxide, water, and other inorganic raw materials: a plant, alga, or autotrophic bacterium | |
| 203460463 | Consumer | An organism that obtains its food by eating plants or by eating animals that have eaten plants | |
| 203460464 | Decomposer | A consumer that derives its energy from nonliving organic material | |
| 203460465 | Emergent Properties | New properties that emerge with each step upward in the hierarchy of life, owing to the arrangement and interactions of parts as complexity increases | |
| 203460466 | System | A more complex organization formed from a combination of components | |
| 203460467 | Prokaryotic cell | A type of cell lacking a membrane-enclosed nucleus and other membrane-enclosed organelles; found only in the domains Bacteria and Archaea | |
| 203460468 | Eukaryotic cell | A type of cell that has a membrane-enclosed nucleus and other membrane-enclosed organelles. All organisms except bacteria and archaea are composed of eukaryotic cells | |
| 203460469 | species | a group whose members possess similar anatomical characteristics and have the ability to interbreed. | |
| 203460470 | Taxonomy | The branch of biology concerned with identifying, naming, and classifying species | |
| 203460471 | Kingdom | In classification, the broad taxonomic category above phylum or division | |
| 203460472 | Domain | A taxonomic category above the kingdom level. The three domains of life are Archaea, Bacteria, and Eukarya | |
| 203460473 | Bacteria | One of two prokaryotic domains of life, the other being Archaea | |
| 203460474 | Archaea | One of two prokaryotic domains of life, the other being bacteria | |
| 203460475 | Prokaryote | An organism with prokaryotic cells | |
| 203460476 | Theory | A widely accepted explanatory idea that is broad in scope and supported by a large body of evidence | |
| 203460477 | Natural Selection | Differential success in reproduction by different phenotypes resulting from interactions with the environment. Evolution occurs when natural selection produces changes in the relative frequencies of alleles in a population's gene pool | |
| 203460478 | Evolutionary adaption | a inherited characteristic that enhances an organism's ability to survive and reproduce in a particular environment | |
| 203460479 | hypothesis | A tentative explanation a scientist proposes for a specific phenomenon that has been observed | |
| 203460480 | controlled experiment | A component of the process of science whereby a scientist carries out two parallel tests, an experimental test and a control test. The experimental test differs from the control by one factor, the variable | |
| 203460481 | technology | The practical application of scientific knowledge |
