Question

Distinguish between microevolution and macroevolution. Explain how forest
organisms (producers and consumers) separated by a highway could evolve into
different species.

Describe three factors that influence a species’ chance of successfully
adapting to a rapid change in its environment.

Identify the mechanisms by which albedo and the angle of the sun’s rays cause
colder temperatures at high latitudes. Why does albedo in high latitudes
change as Earth warms? (Identify the feedback loop involved in this process.)
