What to Focus On

  • An ecosystem includes living and non-living parts.
  • Biotic components are living organisms.
  • Abiotic components are non-living factors.
  • Green plants are producers or autotrophs.
  • Herbivores are primary consumers.
  • Carnivores are secondary consumers.
  • A food chain is linear.
  • Each organism eats the one below it.
  • Food chains usually have 2 to 5 steps.

Common Mistakes to Avoid

Every organism in a food chain has the same trophic level in all examples.

Food chain length can be any number of steps, including seven or more.

Food web is just another name for food chain.
