| Habitat | the natural environment where a plant, animal, or other organism lives, grows, and reproduces. |
| Natural selection | the evolutionary process where organisms with traits better suited to their environment survive and reproduce more successfully, passing those advantageous traits on to future generations. |
| Hypothesis | a proposed, testable, and falsifiable explanation or prediction for an observation, phenomenon, or research question. |
| Variation | Variation is any difference, change, or deviation in form, position, condition, or amount from a norm, standard, or expected state. |
| Species | the basic unit of biological classification and a group of individual organisms that share common traits and can interbreed to produce fertile offspring. |
| Evolve | to develop, change, or grow gradually over time, often moving from a simpler state to a more complex, advanced, or better-adapted form. |
| Population | the total number of people, animals, or living organisms inhabiting a specific geographic area or region at a given time. |
| Predator | an organism that naturally hunts, kills, and consumes other organisms (its prey) for food. |
| Prey | an animal that is hunted, caught, and killed for food by another animal (a predator). |
| Environment | the set of physical, chemical, biological, social, or cultural conditions and surroundings that affect the growth, health, development, and survival of a living organism or system. |
| Evolution | a gradual process of change, development, or growth from one state to another over time. The term applies across science, language, and general history, with its most prominent use in biology. |
| Decomposers | organisms that break down dead plants, animal carcasses, and organic waste into simpler inorganic substances like water, carbon dioxide, nitrogen, and phosphorus. |
| Extinction | the state or process in which a group, species, language, or physical phenomenon no longer exists anywhere on Earth. |
| Climate | Climate is the long-term pattern of atmospheric conditions—including temperature, precipitation, humidity, wind, and sunshine—typically averaged over a 30-year period. |
| Hibernate | to spend the winter in a deep, sleep-like state of inactivity to survive cold weather and food shortages |
| Biomes | a large, naturally occurring community of flora (plants) and fauna (animals) that occupies a major geographic habitat. |
| Fitness | the condition of being physically strong and healthy, or the quality of being suitable and qualified for a specific task or environment. |
