| What is a Endangered Species? | It is close to becoming extinct in all parts of a country or large locations. |
| What is a Extirpated Species? | No longer living in one part of a country but can live in other parts. |
| What is a threatened Species? | When a species is likely to become extinct. |
| What is a Special Concerned Species? | Any species with low or declining number IN A RESTRICTED AREA. |
| What is a Indicator Species? | A species that is sensitive to its environment and warns if the ecosystem is off or not right. |
| What is a Trophic Level? | A trophic level is a category for how an organism gains its energy |
| What is a Autotroph? | A producer, something that can create its own food. Found on the first trophic level. |
| What is a Heterotroph? | A consumer, something that cannot create its own food, so it has to feed on other organisms. Found in other trophic levels. |
| Name what each Trophic Level is. | Trophic level #4- Tertiary Consumer Trophic level #3- Secondary Consumer Trophic level #2- Primary Consumer Trophic level #1- Producer |
| What are Food Chains and Food Webs? | Food chains and food webs show the flow of energy from one organism to the next. |
| How can Temperatures affect the number of organisms? | Lower amount of sunlight + Cold temperatures = low producer population |
| What is Photosynthesis? | Solar energy is converted into chemical energy. |
| What is Cellular Respiration? | The process of oxidizing food molecules such as glucose to carbon dioxide and water. Chemical energy of sugar converted to chemical energy. |
| What is Chemosynthesis? | Chemoautotrophs (bacteria) use an alternative energy source to create organic energy molecules. |
| Rule of 10 | Only 10% of the energy transferred from one organism to another. Areas of loss: Waste, Thermal Energy, fuel for Cellular Respiration. |
| Laws of Thermodynamics. | 1st law: Energy can be transferred from one organism to another, it cannot be created or destroyed. 2nd law: Energy transformations are never 100% efficient, some energy is lost (heat) |
| What is a Pyramid of Numbers? | The number of organisms in a food chain that is represented graphically. |
| What is a Pyramid of Biomass? | Shows the total dry mass of organisms at each trophic level of a food chain. |
| What is a Pyramid of Energy? | Shows the total amount of energy transferred through each trophic level. |
