Bio 200: Final Exam with 100% Correct
Solutions
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 earths 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 - ANSWER-Light intensity affects the
temperature of the earth
-ex: equator- hot wet climate
Hadley Cells - ANSWER-named after George Hadley, is a tropical atmospheric
circulation which features rising motion near the equator,
What causes the Seasons? - ANSWER-World is unbalanced, not perfectly vertical,
caused because of our orbit (the tilt)
Rain in the southern hemisphere - ANSWER-More water in atmosphere of southern
-Factors that lead to local variation in climate
Rain Shadows - ANSWER-Coastal mountains cause rain shadows; one side is dry
-Factors that lead to local variation in climate
Slope and local drought - ANSWER-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 - ANSWER-One can be dry (receive more sunlight) while
the other can be moist (woodland)
-Factors that lead to local variation in climate
, Commensalism - ANSWER--Symbioses
-an association between two organisms in which one benefits and the other derives
neither benefit nor harm.
Ammensalism - ANSWER--Symbioses
-is any relationship between organisms of different species in which one organism is
inhibited or destroyed while the other organism remains unaffected
Symbioses - ANSWER-A permanent interaction of two species
Exploitation: - ANSWER-One species lowers the resources of another
Interference - ANSWER-One species prevents the other from gaining access to a
resource
Sympatric - ANSWER-live in close proximity
Allopatric - ANSWER-live apart
limnetic - ANSWER-living in well-lit open surface waters
benthic - ANSWER-the lowest level of the water, including the sediment surface
Resource Partitioning - ANSWER-temporal partitioning of resources
Intraspecific competition - ANSWER--within a given community there are likely to be
multiple individuals of a given species. Individuals undoubtedly interact
Interspecific Competition - ANSWER-May bear on community relationships and
dynamics community ecologists expend more focus
-interactions between or among species
Obligate - ANSWER-at least one of the species must be in relation with the other to
survive
Facultative - ANSWER-beneficial but not necessary for survival
Ectosymbiosis - ANSWER-one individual lives on another
-ex fleas on a dog
Endosymbiosis - ANSWER-one individual live in another
ex intestinal parasite
Trophic - ANSWER--Nutrient related
