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
Cycling of Matter Decomposition Plants Herbivores Predators Nutrients in the Soil Waste and Death Decomposition
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 Micro-organisms Worms Compost Organic Waste Replenish Soil Cycle of Matter
Composting Cycle • The decomposing step within the cycle of matter has its own cycle. • This is the cycle of a compost bin
