8. A group of researchers performed an investigation in which they grew two species of
microscopic aquatic organisms called paramecia in test tubes. The researchers found that both
species grew better alone. When grown together, the growth of one species (A) declined and
the growth of the other species (6) increased until it reached capacity
which statement best describes what would likely happen to these species if they were grown
in a lake instead of a test tube?
A. Over time, species A would outcompete species B for food.
B. Over time, species A would evolve so that it could compete with species B.
C. Over time, species B would survive and pass on its traits to future offspring.
D. Over time, species B would exhaust its food source and begin to rapidly decline.
