Dan Janzen argued that tropical communities contain more species because
__________________________ - ANSWER-tropical environments favor specialized niches, which limits
gene flow and promotes speciation.
Tropical species are __________________________ - ANSWER-most at risk from climate change because
tropical species likely have narrow niches.
True or False? Dan Janzen proposed that speciation occurs more often in the tropics because tropical
species mutate faster. - ANSWER-False; he did not mention faster rates of mutation; he did mention that
there is far more variation in climate in high latitudes than there are in the tropics.
True or False? A more specialized species should occur over a narrower range of altitudes. - ANSWER-
True; a specialist can only handle the small range of conditions and altitudes as the higher you move, the
colder it gets, and the lower you go, the hotter it gets.
Carbon is found only in plants in animals. - ANSWER-False

Carbon dioxide enters the atmosphere when ______________________. - ANSWER-plants burn in a
wildfire, organisms respire, organisms decompose.
Humans influence the carbon cycle by ____________________________. - ANSWER-mining carbon-
based materials that were buried over millions of years, combusting carbon-based fuels to generate
power, planting trees to generate timber for the building industry
The atmosphere is changing because ___________________________. - ANSWER-carbon is being added
faster than it is removed
How might rising CO2 impact an ecosystem? - ANSWER-Increase photosynthesis, carbonic acid decrease
populations in the sea, indirectly increase herbivore density, therefore increase carnivore density.
True or False? When two variables are correlated, an increase in one variable does not necessarily cause
an increase in the other variable. - ANSWER-True; it does not necessarily mean cause and effect.
True or False? To test the hypothesis that greenhouse gases cause global warming, we need to replicate
the observations of warming on Earth by studying multiple planets. - ANSWER-True; experiments need
to be manipulated although it won't be at the scale of the Earth.
Carbon dioxide emitted by human activities will remain in the atmosphere unless humans design
technologies to remove this compound from the air. - ANSWER-False
If the remaining fossilized carbon were combusted the rise in atmospheric carbon dioxide would exceed
the rise observed since 1900. - ANSWER-True
A teleconnection occurs when carbon dioxide from western Europe enters the Indian Ocean and reacts
to form an acid. - ANSWER-True
True or False? When cane toads are added to a community, the number of crimson finches should
decrease. - ANSWER-False; the number of crimson finches should increase and benefit from the
introduction of cane toads as they have a negative affects on those eating them, meaning that they are
not preying on as many crimson finches as they use to.
