Pyrrhocoris apterus, or firebug, is native to Europe and China, and eats the seeds of lime trees and mallow trees
What is the most likely explanation for the fact that a native North
American species, the fir tree, synthesizes a compound that disrupts development of this
European insect?
A. The fir tree benefits from this compound
because its effect on the firebug decreases
competition for resources in its natural
environment.
B. The fir tree benefits from this compound
because its effect on the firebug increases
the survival of fir tree offspring.
C. The fir tree benefits from this compound
because its effect on the firebug increases
predation pressure on its competition.
D. The fir tree benefits from this compound
because its effect on the firebug increases
the survival of other, related members of the
same species.
E. There is likely strong similarity in the
hormone receptors of different insects so that
a compound made by a tree native to North
America has an effect on an insect native to
Europe.
