BIO 182 FINAL EXAM ASU QUESTIONS
AND CORRECT ANSWERS
What are estuaries? ANSW✅✅-A junction between rivers and oceans
-Salinity varies almost daily
-Among the most productive environments (High level of nutrients, shallow water allows for
sunlight)
What is the intertidal zone? ANSW✅✅-Beach that is exposed at low tide and covered at high tide
-Organisms have to adapt to low tide exposure
-High productivity
(RockyPoint)
What is the neretic zone? ANSW✅✅-Extends from intertidal zone to depths of 200 m
-Part of sloping continental plane
-Very productive due to upwelling
(Coral reefs)
What is the oceanic zone? ANSW✅✅-The open ocean
-Sunlight abundant in photic zone but nutrients are scarce
What is the benthic zone? ANSW✅✅-Bottom of the ocean
-Organisms survive on dead bodies of organisms from the photic zone
What are freshwater biomes? ANSW✅✅-Lakes and ponds, rivers and streams, wetlands
What is lake turnover? ANSW✅✅-Occurs in temperate regions
-The nutrients at the bottom of the lake is carried to the top
, -Promotes growth of algae
What is ocean upwelling? ANSW✅✅-Move nutrients from aphotic to photic zone
-Promotes algae growth
-Areas of high biological productivity and diversity
What is water depth? ANSW✅✅-The amount and types of wavelengths available to organisms
change dramatically as the water depth increases
-As the water gets deeper, the light intensity decreases
What physical factors effect the distribution and abundance of organisms in aquatic biomes?
ANSW✅✅-Water depth
-Nutrient availability
-Water movement
-Temperature
What are the types of aquatic biomes and how are they classified? ANSW✅✅-They are classified
by salinity
-Fresh water ( less than 0.1% salt), marine (salt water)
How have humans impacted terrestrial biomes? ANSW✅✅-By physically changing the landscape
-Farming, logging, & urban development
-Indirect effects: pollution, invasive species, climate change
Describe the arctic tundra ANSW✅✅-Dominated by small shrubs
-Very low temps
-Very low annual rainfall
Describe boreal forests ANSW✅✅-Forms in sub-arctic
-Dominated by highly cold tolerant trees
-Very cold winters and short, cool summers
-Low precipitation
