- aphotic zone
- a 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.
- b The driest of all terrestrial biomes, characterized by low and unpredictable rainfall (less than 30 cm per year).
- c Microscopic algae and cyanobacteria that carry out photosynthesis in the photic zone.
- d 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.
- 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.

- Submerged parts of continents.
- (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.
- (Aka deciduous forests/broadleaf forests) Biomes in midlatitude regions where the moisture is sufficient enough to support the growth of large trees. Temperatures range from very cold in the winter to hot in the summer, with average rainfall around 75 to 150 cm.
- All open water in the ocean.
- (Aka rainforest) These biomes occur in equatorial areas where the temperature is warm and the days are 11-12 hours long year-round. Rainfall is variable (200-400 cm per year) and the amount of organism diversity is extremely high.
5 True/False Questions
trade winds → Dry air that descends and spreads back toward the equator; these cooling winds dominate the equator.
permafrost → Continuously frozen subsoil.
ocean currents → All open water in the ocean.
biomes → Major types of ecological associations that occupy broad geographic regions of land or water, influenced by abiotic factors.
tropics → 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.
