Trees are rare in the savanna biome because of
A) insufficient
annual precipitation.
B) acidic soils.
C) extreme winter
temperatures.
D) large variations in seasonal rainfall.
E) permafrost.
extreme winter temperatures.
Which of the following statements best describes the effect of
climate on biome distribution?
A) Average annual temperature and
precipitation are sufficient to predict which biome will be
found
in an area.
B) Seasonal fluctuation of temperature is not a
limiting factor in biome distribution if areas have
the same
annual temperature and precipitation means.
C) Not only is the
average climate important in determining biome distribution, but so is
the
pattern of climatic variation.
D) Temperate forests and
grasslands are different biomes because they receive a different
quality
and quantity of sunlight, even though they have
essentially the same annual temperature
and
precipitation.
E) Correlation of climate with biome
distribution is sufficient to determine the cause of biome
patterns.
Not only is the average climate important in determining biome
distribution, but so is the
pattern of climatic variation.
In the ecological development of terrestrial biomes, which factor is
most dependent on all the
others?
A) the species of

B) prevailing temperature
C) prevailing
rainfall
D) mineral nutrient availability
E) soil structure
