BIO 200: FINAL EXAM QUESTIONS
AND ANSWERS
Ecology - Correct Answers -The study of distribution and abundance
Ecology causes evolution - Correct Answers -How is ecology related to evolution?
Abiotic - Correct Answers -Non-living
Biotic - Correct Answers -Living
Three factors that influence climate - Correct Answers --Variation in light intensity
-Angle of earths axis
-Variation in local conditions
Intensity of sunlight on Earth varies - Correct Answers --Angle of sunlight affects
intensity
-causes equator to be hottest part
Effect of light intensity on temperature - Correct Answers -Light intensity affects the
temperature of the earth
-ex: equator- hot wet climate
Hadley Cells - Correct Answers -named after George Hadley, is a tropical atmospheric
circulation which features rising motion near the equator,
What causes the Seasons? - Correct Answers -World is unbalanced, not perfectly
vertical, caused because of our orbit (the tilt)
Rain in the southern hemisphere - Correct Answers -More water in atmosphere of
southern
-Factors that lead to local variation in climate
Rain Shadows - Correct Answers -Coastal mountains cause rain shadows; one side is
dry
-Factors that lead to local variation in climate
, Slope and local drought - Correct Answers -Steep slopes can be locally dry; valley
between is place for tree to grow
-Factors that lead to local variation in climate
North vs. South facing slopes - Correct Answers -One can be dry (receive more
sunlight) while the other can be moist (woodland)
-Factors that lead to local variation in climate
Elevation and Temperature - Correct Answers -Elevation leads to cooling. Elevation
lowers temperature
-Factors that lead to local variation in climate
Lake effect snow - Correct Answers -Produced in winter when cold winds warmer lake
water. Water will stay warmer longer than air. Bring lots of snow.
-Factors that lead to local variation in climate
El nino - Correct Answers --Less predictable global effects on climate
-The flow of current reverse so warm and cold water flows to South America
La Nina - Correct Answers --Less predictable global effects on climate
-Cold water currents reach farther west (Reverse Nino)
Pacific decadal oscillation - Correct Answers --Less predictable global effects on climate
-Shift in surface temperature of worth pacific
-Switch between cold and warm phases
-effects climate
Stochasticity - Correct Answers -Process outcomes cannot always be predicted
Convergence in traits and habitats - Correct Answers --powerful force
-evidence at all levels in the tree of life
-explains why our certain habitat is recognizable to us
Biomes - Correct Answers --very large regions of the earth whose distribution depends
on the amount of Temperature and Rainfall
Tundra - Correct Answers -Found in arctic at high elevations
-Vegetation is low in arctic tundra
-permafrost
-frozen desert
-insects are abundant
-reindeer, caribou, arctic wolves, arctic foxes, arctic hares, polar bears
Tropical Rain Forest - Correct Answers --Found near the equator with abundant rainfall,
stable temperatures, and high humidity
-most diversity
