Cycling of Matter

What will we learn? Cycling of matter within living systems Example of living system: compost bin http://climatelab.org/@api/deki/files/591/=compost.jpg

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
