After looking at the accompanying figure, what can be said about productivity in this ecosystem?
-About 90% of the energy is lost between most trophic levels.
-Nothing can be said based on this information.
-Productivity increases with each trophic level.

If the Earth were to reorient such that the North Pole always received direct sunlight (always faced the
Sun), how would that change Earth's climate?
-The equators would not change in climate.
-The South Pole would get colder.
-The equators would get warmer.
-The North Pole would get more wind. - (answer) -The South Pole would get colder.
If the flow of energy in an arctic ecosystem goes through a simple food chain, perhaps involving humans,
starting from phytoplankton to zooplankton to fish to seals to polar bears, then which of the following
could be true?
-Seal populations are larger than fish populations.
-Seal meat probably contains the lowest concentrations of fat-soluble toxins.
-Polar bears can provide more food for humans than seals can.
-The total biomass of the fish is lower than that of the seals.
-Fish can potentially provide more food for humans than seal meat. - (answer) -Fish can potentially
provide more food for humans than seal meat.
Imagine that a deep temperate-zone lake did not turn over during the spring and fall seasons. Based on
the physical and biological properties of limnetic ecosystems, what would be the difference from normal
seasonal turnover?
-Lakes would suffer a nutrient depletion in surface layers.
-An algal bloom of algae would result every spring.
-The lake would be uniformly cold during the winter and summer.
