ASU BIO 182 Exam 4 Questions & Answers
realized niche - CORRECT ANSWER-describes that part of the fundamental
niche actually occupied by the species
fundamental niche - CORRECT ANSWER-The full range of environmental
conditions and resources an organism can possibly occupy and use, especially
when limiting factors are absent in its habitat.
What contributes to the massive increases in atmospheric CO2? - CORRECT
ANSWER-burning & mining of fossil fuels
What fuels the production of most electricity? - CORRECT ANSWER-coal
What are the fluxes? - CORRECT ANSWER-carbon, nitrogen, & water
Where does the most diversity occur? - CORRECT ANSWER-The equator
Causes of tropical biodiversity - CORRECT ANSWER-longer history, more
competition, more mutualism, more predation, smaller populations, greater
productivity, & greater stability
primary productivity - CORRECT ANSWER-rate at which plants and other
photosynthetic organisms produce organic compounds in an ecosystem
Species occur more in the tropics because... - CORRECT ANSWER-tropical
species have specialized niches
A specialized species should occur over... - CORRECT ANSWER-small range of
altitudes and latitudes
Is tropical biodiversity just about specialization? - CORRECT ANSWER-Hotter
species experience more mutation
Faster mutation in the tropics could... - CORRECT ANSWER-promote speciation
in isolated populations and promote extinction by creating deleterious alleles
