parents in some ways, Living or-
ganisms use energy and materials
to grow ,develop, and reproduce.
These life processes involve a set
of chemical reactions called metab-
olism (B) . Organisms have means of
detecting a change in their environ-
ment and responding to this stimu-
lus (D) . Most organisms require that
their internal environments remain in
a fairly constant range, and so they
maintain homeostasis (E) . The abili-
ty of a group of organisms to change,
or evolve (C) over time helps popu-
lations survive in an ever-changing
environment.
