Principle of Adaptation

• The way a life system looks and behaves is not a
  random occurrence or accident, it is the result
  of millions of years of changing to better
  survive in a given environment.

12
Principle of Diversity

• Over time, changes in environmental conditions
  have led to the development of variety within
  each level of organization.

13
Principle of Energy Flow

• Energy cannot be created, destroyed, or recycled
  in an ecosystem, and energy quality is always
  degraded to less-useful energy after it is
  converted from one form to another. Life depends
  on the one-way flow of high-quality energy from
  the sun through Earths life systems and
  eventually back into space as low-quality heat.

14
Principle of Growth Development

• The living components in an environment follow a
  basic pattern of growth where upon reaching the
  maximum number of living things which that
  environment can support, the rate of growth
  slows.

15
Principle of Limits

• Ecological processes are altered the environment
  can withstand much stress and abuse, but there
  are limits to how much can be tolerated by the
  living systems whose niche occurs there.

16
Principle of Behavior

• The different ways organisms act can have
  different impacts on the survival of organisms.
  Living systems have behavioral responses to
  stress and disturbances responses that enhance
  survival.

Principle of Regulation
http//www.globalchange.umich.edu/globalchange1/cu
rrent/labs/pred_prey/lab9.html

• Energy is spent or a signal is sent to increase
  or decrease some function in order to keep the
  environment balanced.

18
Principle of Emergent Properties

• When different levels of organization are
  functioning together, new properties are created
  that were not operational at lower levels.

When an animal eats a plant, it is getting energy
that came from the sun. energy flow Even over
thousands of years, the leaves of a tree species
can never change their shape. adaptation Life
in the ocean would not change if the oceans
temperature rose without stopping. limits An
ecosystem would not change if a new type of
organism moved into it. emergent properties
