  1. Cycling of Matter

  2. What will we learn? • Cycling of matter within living systems • Example of living system: compost bin

  3. Conservation of Matter • Matter of a closed system will remain constant over time • Matter is not created or destroyed but transformed into more complex forms

  4. Cycling of Matter Decomposition Plants Herbivores Predators Nutrients in the Soil Waste and Death Decomposition

  5. Decomposition • Break down of organic matter into simpler forms of matter AB  A+B • Complex plants break down into the major elements that compose them like carbon, nitrogen, phosphorous and more. C + N + P + …

  6. Composting • Break down of Matter

  7. How does the matter break down? • Micro-organisms • Bacteria • Actinomycetes • Fungi • Protozoa • Rotifers • Worms

  8. Ingredients for Successful Composting • Carbon source (browns) • Nitrogen source (greens) • Water • Oxygen

  9. Composting Cycle Micro-organisms Worms Compost Organic Waste Replenish Soil Cycle of Matter

  10. Composting Cycle • The decomposing step within the cycle of matter has its own cycle. • This is the cycle of a compost bin
