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 http://www.fordesigner.com/pic/zip/200932910221684377801.jpg
Cycling of Matter Decomposition 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 Cycle of Matter Replenish Soil Micro-organisms Worms Organic Waste Cycle of Matter Replenish Soil
Composting Cycle The decomposing step within the cycle of matter has its own cycle. This is the cycle of a compost bin http://www.swa.org/pdf/activity_sheets/compost_activity_sheet.pdf
