Natural selection
| Question | Answer |
|---|---|
| Charles Darwin | A scientist who made the theory of evolution by natural selection after studying variation of living things |
| Migration | the movement of animals from one place to another |
| Adaption | any heritable physical or behavioral trait that helps an organism survive and reproduce in its environment |
| Habitat | the natural environment or "home" where a plant, animal, or other organism lives and grows |
| Natural selection | an evolutionary mechanism where organisms with inherited traits that better suit their environment are more likely to survive, reproduce, and pass those advantageous traits on to future generations |
| Hypothesis | a tentative, testable, and falsifiable proposed explanation for a natural phenomenon or observation |
| Variation | the differences in physical traits, genetic makeup, or behaviors among individuals of the same species or across different populations. |
| Species | the most basic and specific unit of classification in the biological Taxonomy hierarchy |
| Evolve | the change in the heritable characteristics of biological populations over successive generations |
| Population | a group of individual organisms of the same species that live in the same geographic area at the same time and are capable of interbreeding |
| Predator | an organism that hunts, kills, and consumes another organism—known as its prey—to obtain energy and nutrients |
| Prey | any organism that is hunted, attacked, and consumed by a predator for food or energy |
| Environment | the complex system of physical, chemical, and biological factors, along with surrounding conditions, that act upon an organism or an ecological community and determine its survival and development |
| Evolution | the change in the heritable traits of biological populations over successive generations |
| Decomposers | an organism that breaks down dead plants, animals, and organic waste into simpler inorganic substances |
| Extinction | the complete and permanent disappearance of a species, subspecies, or group of taxa when its last remaining member dies out |
| Climate | the scientific study of Earth's climate |
| Hibernate | a state of deep metabolic depression and physical inactivity in animals, characterized by a severely reduced heart rate, slow breathing, and a drastic drop in body temperature to conserve energy during harsh winter conditions or food scarcity |
