Terms | Definitions |
|---|---|
 abiotic | relating to non-living parts of an environment. Examples are sunlight, soil, moisture, and temperature |
| biome | the largest division of the biosphere, which includes large regions with similar biotic components (plants and animals) and similar abiotic components (temperature and amount of rainfall) |
| biotic | relating to living organisms such as plants, animals, fungi, and bacteria |
| climate | the average conditions of the atmosphere (percipitation and temperature and humidity) in a large region over 30 years |
| climatograph | a graph of climate data for a specific region; the data are usually obtained over 30 years from local weather stations |
| terrestrial | relating too the land (ex. land bass biomes) |
| latitude | the distance measured in degrees north or south from the equator |
| elevation | the height of a land mass above sea level |
| habitat | is the place in which an organism lives |
| adaptations | characteristics that enable an organism to better survive |
| structural adaptation | a physical feature of an organism's body having a specific function that contributes to the survival of the organism |
| physiological adaptation | a physical or chemical event that occurs within the body of an organism and enables survival |
| behavioral adaptation | what an organism does to survive the unique conditions of it's environment. These adaptations may include how the organism feeds, mates, cares for its young, hibernates or borrow to escape predators |
| temperature, precipitation and latitude | influence the characteristics of biomes and distribution of biomes on Earth |
| tundra | located in the upper northern hemisphere; very cold and dry. Due to permanently frozen soil, plant are short and there are few trees |
| boreal forest | found in the far north; below freezing half the year. Mainly coniferous (cone-bearing) trees |
| temperate deciduous forest | located in temperate regions, mostly eastern North America, eastern Asia and western Europe. Trees lose their leaves in winter. Large seasonal changes with four distinct seasons |
| temperate rainforest | found along coastlines where oceans winds drop a large amount of moisture. Cool and very wet, allowing trees (mainly evergreens) to grow very tall |
| grassland | occurs in temperate regions, mostly eastern North America, Eastern Asia, and western Europe |
| tropical rainforest | found in a wide band around the equator. Wet and warm year-around, allowing growth of a dense canopy of tall trees |
| desert | occur in temperate and tropical regions; days are hot and nights are cold. Rainfalls minimal and plants and animals are adapted to reduce water loss |
| permanent ice | includes the polar land and masses and large polar ice caps. The few animals thatlive here are well insulated against the extreme cold |
