5664112867ProducersMake their own food17
5664112868Autotrophsany organism capable of self-nourishment by using inorganic materials as a source of nutrients and using photosynthesis or chemosynthesis as a source of energy, as most plants and certain bacteria and protists.18
5664112869ConsumersAn organism that obtains energy and nutrients by feeding on other organisms or their remains.19
5664112870HeterotrophsAn organism that obtains organic food molecules by eating other organisms or their by-products.20

5664112876AdaptationA trait that helps an organism survive and reproduce26
5664112877MutationA rare change in the DNA of a gene, ultimately creating genetic diversity.27
5664112878Gene TraitRepresented in pairs with an upper case letter for the dominant (A) and a lower case letter for the recessive (a). Since half the genetic material is from each parent, the offspring's traits are represented as a combination of these.28
5664112879ChromosomeA threadlike, gene-carrying structure found in the nucleus. Each _____ consists of one very long DNA molecule and associated proteins.29
5664112880Gene poolCombined genetic information of all the members of a particular population30
5664112881Natural SelectionA process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits.31
5664112882ExtinctionA term that typically describes a species that no longer has any known living individuals.32
5664112883Plate TectonicsA theory stating that the earth's surface is broken into plates that move. Geological processes, such as continental drift, volcanoes, and earthquakes, resulting from plate movement33
5664112884WeatheringThe breaking down of rocks and other materials on the Earth's surface.34
5664112885Climate ChangeChange in the statistical properties of the climate system when considered over periods of decades35
5664112886RocksA naturally formed aggregate, or mixture, of minerals; have varied chemical compositions36
5664112887MineralsA solid inorganic substance of natural occurrence.37
5664112888ClimateOverall weather in an area over a long period of time38
5664112889WeatherThe condition of Earth's atmosphere at a particular time and place.39
