What to Focus On

  • Ecosystem analysis studies interactions, processes, and feedback mechanisms.
  • Biotic components are producers, consumers, and decomposers.
  • Abiotic components include sunlight, water, air, soil, temperature, and minerals.

  • Limiting factors restrict growth, abundance, or distribution.
  • Limiting factors may be physical or biological.
  • Liebig's Law of the Minimum states that the scarcest resource limits growth.

  • Critical variables strongly affect survival, growth, and reproduction.
  • Temperature, light, water, oxygen, nutrients, and pH are major critical variables.
  • State variables describe the current condition of an ecosystem.

Common Mistakes to Avoid

An ecosystem is just a collection of living organisms in one place.

Energy and nutrients move through ecosystems in the same way.

A limiting factor is any factor that is present in large quantity or any factor that is harmful.

Memory Tips

Ecosystem as an interconnected self-regulating system

Biotic and abiotic components

Energy flow and nutrient cycling

Decomposers
