How do matter and energy link organisms to each other and their environments?

  1. Living organisms have the capability of producing populations of unlimited size, but the environment can support only a limited number of individuals from each species.
  2. Changes in an ecosystem can result from changes in climate, human activity, introduction of nonnative species, or changes in population size.
  3. Water, carbon and nitrogen cycle between abiotic resources and organic matter in the ecosystem and oxygen cycles through photosynthesis and respiration.

Extra Help

I am available for extra help most days:

  • Before school from 7:00 to 7:20 AM
  • During the day when I am free
  • After school until 3:00 PM.

Please check with me if you plan on staying after to make sure I don't have a meeting or other obligation. Faculty meetings are usually Wednesday after school.

You can email questions at any time:

You should not expect an immediate answer after 10 PM or while I am teaching.
