5 Multiple choice questions
- The significant environmental problem by which semiarid regions are converted to desert.
- 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.
- The biome located in the Arctic surrounding the North Pole and Alpine meadows, characterized by very long, cold, harsh winters and minuscule summers. Ground is covered in permafrost most of the year.
- Microscopic algae and cyanobacteria that carry out photosynthesis in the photic zone.
- (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
estuary → A biome that occurs where a freshwater stream or river merges with the ocean.
permafrost → The driest of all terrestrial biomes, characterized by low and unpredictable rainfall (less than 30 cm per year).
temperate zones → 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.
benthic realm → The seafloor.
intertidal zone → The depth of light penetration, a maximum of 200 meters, in the ocean.
