# Unit Review: Key Concepts
  • Living things get their energy through food chains.
  • Most of the matter that makes up plants comes from the air.
  • All food can be traced back to plants.
  • Decomposers break down dead things and recycle nutrients.
  • Organisms in an ecosystem depend on one another to cycle energy and nutrients.
  • All energy in an ecosystem first came from the Sun.

In today's activity, you will evaluate a proposal for an ecosystem inside a Mars habitat. Using what you learned while designing your own plan throughout the unit, you will decide if the proposed Mars ecosystem plan will keep humans alive.

We'll walk you through it, step by step.
