1
Chapter 6 Sections 6.3 and 6.4 Stability in the
Ecosystem
2
Stability
  • The measure of how easily an ecosystem is
    affected by a disturbance and how quickly it
    returns to its original condition after a
    disturbance.

3
Equilibrium
  • Is a state of balance.
  • The disrupted ecosystem will return to this state
    of balance or equilibrium.

4
Disrupted Ecosystem
5
Natural Rule
  • Species and whole ecosystems evolve and may die
    out, but new species and ecosystems can evolve to
    replace them.

Chaos Theory
  • Suggests that ecosystems may be sensitive to very
    small changes, and that the initial state of an
    ecosystem is crucial to its later development.

7
Human Impacts
  • Habitat destruction.
  • Introduction of invasive species.
  • Pollution of water, soil and air.
