| 1. Biome 2. Ecosystem 3. Community 4. Population 5. Organism | List the five levels of organization for an environment in order |
| Abiotic | Non-living parts of an ecosystem |
| Biotic | Living parts of an ecosystem |
| Food chain | Pathway which energy follows from producer to consumer |
| Producer | Organism that is capable of making its own food |
| Consumer | Organism that relies on producers as a food source |
| Predator | One that captures, kills, and consumes another |
| Prey | One that us captured, killed and consumed by another |
| Biotic potential | Ability of an ecosystem to maintain life |
| Carrying capacity | Number of individuals of a species that an ecosystem can support |
| Succession | Sequential replacement of populations in an ecosystem |
| Biome | Geographic area with characteristic plants, animals,& climate |
| Ecosystem | All the biotic and abiotic parts of an environment |
| Ecology | Study of organisms and their environment |
| Biosphere | Area on and around earth where life exists |
| Community | All the populations in an area |
| Population | All the members of a species in an area |
| Species | Group of organisms capable of producing fertile offspring in the natural environment |
| Habitat | Physical area where an organism lives |
| Niche | The way of life of a species, the role the species plays in its ecosystem |
| Climate | The amount of rain fall and temperature in an area |
| Immigration | Movement of individuals into a population |
| Emigration | Movement of individuals out of a population |
| Herbivore | Animals that eat only plants |
| Carnivore | Animals that eat only other animals |
| Omnivore | Animals that eat both plants and animals |
| climate | a region's long-term weather pattern. The "usual" weather. |
| polar region | biome extends from above the 60° North latitude and 60° South latitude, coldest biome, very dry with sparse precipitation |
| tundra | biome found only in the Northern Hemisphere just south of the North Polar Region, very cold and dry, permanently frozen ground called permafrost |
| taiga | biome also called Boreal Forest, south of Tundra in the Northern Hemisphere and in Andes mountains of South America, cold, moderate precipitation, characterized by coniferous trees (needle-bearing trees) |
| temperate forest | biome south of Taiga in Northern Hemisphere in mid-latitudes, high amounts of precipitation, warm/hot during summer and cold during winter |
| temperate grasslands | biome near lower mid-latitudes, little to moderate precipitation, extreme seasonal changes - hot summer and cold winters, very fertile soil |
| desert | biome located along and near the Tropic of Cancer and Capricorn, very hot during day (often cold at night), driest biome with little to no precipitation, very little vegetation and animals |
| savanna | biome similar to Temperate Grasslands, located in lower mid-latitudes most often just south of the Tropic of Cancer and just north of the Tropic of Capricorn, wet summer and dry "winter" and the temperature is always warm, only rains during the summer |
| heterotroph | an organism that obtains energy by feeding on other organisms` |
| autotroph | an organism that makes its own energy using abiotic factors |
| primary consumer | Organisims that eat autotrophs. these organisms are called herbivores |
| tertiary consumer | A carnivore that it at the top most level of the food chain and feeds on secondary consumers. |
| secondary consumer | Organisms that get energy from primary consumers. they're carnivores and omnivores. |
| producer | organisms that makes own energy through photosynthesis or chemosynthesis --autotroph |
| consumer | Heterotrophs that must get food from an outside source |
| saprotroph | Organisms that invade the tissues of other organisms (usually dead) digest and then absorb nutrient. for example molds and bacteria |
| decomposer | organisms that break down wastes and dead organisms and return raw materials to the environment |
