- aphotic zone
- a A biome that is transitional between an aquatic ecosystem and a terrestrial one.
- b The zone below the photic zone in the ocean, comprising of the twilight zone (200 to 1,000 m) and the lightless zone that is below 1,000 meters.
- c Major types of ecological associations that occupy broad geographic regions of land or water, influenced by abiotic factors.
- d The region surrounding the equator between latitudes 23.5 degrees north (the Tropic of Cancer) and 23.5 degrees south (the Tropic of Capricorn), which experiences the greatest annual input and the least seasonal variation in solar radiation.
- e A biome dominated by grasses and scattered trees with a year-round warm temperature. The soil is poor and there is a lack of moisture. Rainfall is is around 30-50 cm per year.
5 Multiple choice questions
- The latitudes and the tropics and the Arctic Circle in the north and the Antarctic Circle in the south. They have seasonal variations in climate and more moderate temperatures than the tropics or polar zones.
- A biome characterized by dense, spiny shrubs with tough evergreen leaves. The climate generally results from cool ocean currents circulating offshore which produce mild, rainy winters and hot, dry summers.
- (Aka taiga) A biome found south of the Arctic Circle dominated by cone-bearing evergreen trees such as spruce, pine, fir, and hemlock. They have long, cold winters and short, wet summers, with considerable precipitation.
- Treeless grasslands found in regions with relatively cold winters and average between 25 and 75 cm of rainfall a year.
- An area of calm or very light winds caused by moist air at the equator rising due to being heated by the direct rays of the sun.
5 True/False questions
desertification → The significant environmental problem by which semiarid regions are converted to desert.
permafrost → The driest of all terrestrial biomes, characterized by low and unpredictable rainfall (less than 30 cm per year).
benthic realm → All open water in the ocean.
intertidal zone → Place where the ocean meets the land and the shore is pounded by waves during high tide and is exposed to sun and drying winds during low tide.
phytoplankton → Small, drifting animals located in the pelagic photic zone.
