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

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

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 + …

Composting• Break down of Matter

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

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

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