THE CYCLE OF MATTER

• Biodegradable Able to be broken down by
  bacteria or other living organisms.
• Nature returns living organisms back to the
  earth after they die. As the organisms decompose,
  the nutrients they contain are broken down and
  returned to the soil, where they are available to
  be used by future plants and animals.
