|---|---|
| Evolution | a change in a populations gene pool over time |
| Gene | A sequence of DNA that codes for a particular trait |
| Mutations | Changes in DNA |
| Genetic Drift | biological evolution that occurs by chance |
| Natural Selection | Traits that improve an organisms chances for survival and reproduction are passed more frequently for future generations that do not. |
| Fitness | how reproductively successful an organism is in its environment |
| Adaptation | A heritable trait that increases an individuals fitness |
| Artificial Selection | Selection conducted under human direction |
| Specialization | The process by which new species are generated |
| extinction | The disappearance of a species from earth is called extinction |
| niche | its use of resources and its functional role in a community |
| Tolerance | The ability to survive and reproduce under changing environmental conditions |
| resource partitioning | species divide the resource they use in common by specializing in different ways |
| predation | an individual of one species, a predator, hunts, capture, kill, and consumes an individual of another species. |
| coevolution | two species evolve in response to changes in eachother |
| parasitism | when a parasite organism depends on the host for nourishment |
| symbiosis | long-lasting and physically close relationship in which at least one organism benefits |
| \herbivory | an interaction which an animal feeds on plants. |
| mutualism | a relationship in which two or more species benefit |
| commensalism | a relationship in which one species benefits and one is unaffected. |
| primary producers | Capture energy from the sun or from chemicals and store it in bonds of sugars, making energy available for the rest of the community, |
| Photosynthesis | process by which primary producers use sunlight into chemical energy |
| chemosynthesis | process of turning carbon dioxide and water into sugars |
| consumers | organisms that rely on other organisms for energy and nutrients |
| cellular respiration | process of which organisms use oxygen to release the chemical energy of sugars such as glucose. |
| herbivore | organisms that consume producers. |
| carnivores | consumers that kill and eat other animals |
| omnivores | animals that eat both herbs and other animals. |
| detritivores | ecosystems recyclers that consume dead things and waste product. |
| decomposers | break down nonliving matter into simpler parts, fungi and bacteria. |
| trophic level | When matter and energy move through feeding on one another. |
| biomass | the amount of living tissue biomass has |
| food chain | linear series of feeding relationships. |
| food web | a visual map of feeding relationships and energy flow. |
| keystone species | a species that has wide-reaching impact on a community |
| succession | a community experiences a somewhat predictable series of changes over time. |
| primary success | when a disturbance is so severe that no vegetation or soil life remains. |
| pioneer species | species that colonize the newly exposed land first. |
| secondary succession | when a disturbs economy's but doesn't destroy all things. |
| invasive species | a nonnative organism that spreads widely in a community. |
