|---|---|
| Organism | a member of a species |
| Population | all of one species living in a given area |
| Community | all the poopulations in a given area |
| Ecosystem | all the living and nonliving factors in a given area |
| Biome | similar types of enviornments |
| Biosphere | all the biomes on earth |
| Tropical Rain Forest | warm temps; abundent rainfall; very dense vegetation and an immense variety of species of plants and animals |
| Savanna | tropical grassland with scattered. found in parts of Africa and South Amercia; Temps are high, rainfall is moderate and there is a long dry season. |
| Desert | very little rainfall; Plants have tough waxy coats to conserve water; Many animals burrow in the ground to avoid the heat. |
| Temperate Deciduous Forest | rainfall is abundent, summers are relatively long, winters are rather cold; Typical plants are broad leaved trees that are DECIDUOUS |

| Biotic Factor | Biological factors that can affect a community |
| Food Chains | the exchange of energy from one organism to another until there are no more organisms involved; linear exchange |
| Food Web | All the different food chains together in a particular biome |
| Symbiosis | two organisms live close enough to have a relationship |
| Mutualism | both organisms benefit in the relationship |
| Commensalism | one organism benefits in the relationship and the other is neither harmed nor affected |
| Parasitism | one organism benefits in the relationship and the other organism is harmed |
| Trophic Level | feeding position in chain |
| Pyramids of Energy | a model illustrating that energy decreases at each succeeding trophic level |
| Biomass | amount of living tissue |
| Pyramid of Biomass | represents the amount of potential food available for each trophic level |
| Pyramid of Numbers | shows relative number of individual organisms at each trophic level |
| Carbon Cycle | involves photosynthesis & respiration |
