| Ecology | Scientific study of how organisms interact within their environment |
| Organism | any single living thing |
| Population | any species of organisms that interbreeds and lives in a particular geographic area |
| Community | all of the populations that inhabit a particular geographic area |
| Ecosystem | this is made up of all of the populations and non-living elements including: water, solar energy, wind, temperature, soil, mountains, etc. within a particular area |
| Biosphere | the global ecosystem; it consists of all biotic (living) and abiotic (non-living) elements that exist from an altitude of several kilometers of the earth’s atmosphere to the depths of the deepest parts of the ocean |
| Trade Winds | wings that are moving back toward the equator from 23/5 degrees north and south latitudes |
| Temperate Zones | areas between 23.5 degrees north latitude and the North Pole and 23.5 degrees south latitude and the South Pole |
| Terrestrial Biomes | any biomes occurring on land |
| Tundra | biome consisting of the northernmost land area on earth, known for long cold winters and short summers with long days |
| Permafrost | soil that remains frozen, commonly found in regions of the tundra |
| Taiga | biome south of the tundra that is dominated by conifer forests |
| Temperate Forest | biome that lies in the temperate regions and characterized by deciduous trees (trees that shed their leaves annually) |
| Tropical Rainforest | biome located in the lowlands near the equator, characterized by the greatest diversity of organisms |
| Canopy | tallest trees which form the top layer in a forest |
| Epiphytes | tropical plants that grow on other trees in order to reach heights where they can receive adequate sun for photosynthesis |
| Ectothermic | body temperature-dependent on the temperature of the environment |
| Grasslands | Biome found in the temperate and tropical zones, characterized by reduced amounts of moisture and/or prolonged periods of no moisture--leading agricultural regions of the world today |
| Savanna | Biome of tall-grass grassland with trees found in the tropical zone of the Southern Hemisphere, characterized by the wide variety of animal life |
| Scavengers | animals that eat the remains of dead matter |
| Chaparral | Biome characterized by hot, dry summers and wet autumns and winters |
| Desert | Biome characterized by extremely dry conditions radical changes between excessive daytime heat and freezing temperatures at night |
| Nocturnal | orgamisms most active at night |
