What to Focus On

  • An ecosystem includes living organisms and non-living physical components.
  • A.G. Tansley proposed the concept of ecosystem in 1935.
  • Natural ecosystems are of two types: terrestrial and aquatic.
  • Biotic community means populations of organisms living together in one habitat.
  • Autotrophs are producers.
  • Heterotrophs are consumers.
  • Food chain transfers energy from one organism to another.
  • Trophic level means feeding level.
  • Trees and shrubs are level I in the example chain.

Common Mistakes to Avoid

An ecosystem means only living organisms in one area.

All autotrophs use sunlight to make food.

Consumers are the same as decomposers.
