Carrying Capacity

Sophisticated

Accurately defined.

Graph is clear & accurate, showing growth rate increasing, growth rate slowing, and growth rate stopping with population stabilizing.

Accurately explains why the population line "wiggles" over and under the Carrying Capacity line.

These topics are accurately labeled and explained on the graph:
- lag phase
- exponential growth phase
- deceleration phase
- stable equilibrium phase
