In a graphical representation of an organism's population growth in a given habitat, the growth rate for an organism whose population is increasing according to its biotic potential is best represented by a(n)

A) line with a negative slope.
B) S-shaped curve.
C) flat line (no slope) set at the carrying capacity of the environment.
D) exponential growth curve.
E) flat line (no slope) set at the equilibrium point of environmental resistance versus biotic growth potential.
