      Decomposition is affected

      by:
      A The size of decomposers Correct Answer Incorrect Answer
      B Moisture and temperature Correct Answer Incorrect Answer
      C The age of detritus Correct Answer Incorrect Answer
      D Oxygen content in soil Correct Answer Incorrect Answer

      Solution

      Decomposition is the breakdown of organic matter into simpler inorganic substances by decomposers (bacteria, fungi, and detritivores). The rate of decomposition depends on several factors, but moisture and temperature are the most significant because: Higher temperatures (25-30ยฐC) increase enzyme activity, speeding up microbial metabolism and decomposition. Moisture availability facilitates microbial growth and enzymatic activity. Very low temperatures (cold climates) or extreme dryness (deserts) slow down decomposition.
