Bio 200. Final Exam
Ecology - answer The study of distribution and abundance
Ecology causes evolution - answer How is ecology related to evolution?
Abiotic – answer Non-living
Biotic – answer Living
Three factors that influence climate - answer-Variation in light intensity
-Angle of earth’s axis
-Variation in local conditions
Intensity of sunlight on Earth varies - answer-Angle of sunlight affects intensity
-causes equator to be hottest part
Effect of light intensity on temperature - answerLight intensity affects the temperature of
the earth
-ex: equator- hot wet climate
Hadley Cells - answernamed after George Hadley, is a tropical atmospheric circulation
which features rising motion near the equator,
What causes the Seasons? - answerWorld is unbalanced, not perfectly vertical, caused
because of our orbit (the tilt)
Rain in the southern hemisphere - answerMore water in atmosphere of southern
-Factors that lead to local variation in climate
Rain Shadows - answerCoastal mountains cause rain shadows; one side is dry
-Factors that lead to local variation in climate
Slope and local drought - answerSteep 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 - answerOne can be dry (receive more sunlight) while the
other can be moist (woodland)
-Factors that lead to local variation in climate
Elevation and Temperature - answerElevation leads to cooling. Elevation lowers
temperature
, -Factors that lead to local variation in climate
Lake effect snow - answerProduced 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 - answer-Less predictable global effects on climate
-The flow of current reverse so warm and cold water flows to South America
La Nina - answer-Less predictable global effects on climate
-Cold water currents reach farther west (Reverse Nino)
Pacific decadal oscillation - answer-Less predictable global effects on climate
-Shift in surface temperature of worth pacific
-Switch between cold and warm phases
-effects climate
Stochasticity - answerProcess outcomes cannot always be predicted
Convergence in traits and habitats - answer-powerful force
-evidence at all levels in the tree of life
-explains why our certain habitat is recognizable to us
Biomes - answer-very large regions of the earth whose distribution depends on the
amount of Temperature and Rainfall
Tundra - answerFound 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 - answer-Found near the equator with abundant rainfall, stable
temperatures, and high humidity
-most diversity
-dominant trees are very tall
Desert - answer-most extreme temperature fluctuations
-drought resistant cactus
-most animals are active at night when heat is no longer intense
-rodents, kangaroos, rats, snakes, lizards, insects, spiders
Temperate Grassland - answer-Covers huge areas
-Characterized by low total annual rainfall
-grazing mammals: bison, gazelle, rodents
