The Rate of Decomposition
Decomposition is the breakdown of dead matter by microorganisms, which is essential for recycling nutrients.
Give three factors that increase the rate of decay.
What is The Rate of Decomposition?
"Decomposition is the process by which organic substances are broken down into simpler matter, primarily by bacteria and fungi."
Which term correctly completes this GCSE Biology equation or calculation statement? A ____ is the total of results ÷ number of results

Which option correctly completes the statement? In photosynthesis practicals, moving a lamp ____ increases light intensity
Which answer best completes the statement? Control variables are kept the same for a ____ test
Decay Factors
Temperature: Warmer is faster (up to a point) as enzymes work quicker.
Moisture: Water is needed for the chemical reactions in microorganisms.
Oxygen: Needed for aerobic respiration by the decomposers.
In a vacuum or very cold environment, decomposition stops, which is why we freeze food.
