Learning Objectives

4.7.2.3 Decomposition (biology only)

Content	Key opportunities for skills development
$Students should be able to explain how temperature, water and availability of oxygen affect the rate of decay of biological material.$
$Students should be able to: calculate the changes in the decay of biological material translate information between numerical and graphical form plot and draw appropriate graphs selecting appropriate scales for the axes.$	$MS 1c, 4a, 4c$
$Gardeners and farmers try to provide optimum conditions for rapid decay of waste biological material. The compost produced is used as a natural fertiliser for growing garden plants or crops. Anaerobic decay produces methane gas. Biogas generators can be used to produce methane gas as a fuel.$
