  2. Bacteria   
  3. Fungi  
  4. Animals

The correct answer is: Waste material


    • Decay is the breaking down or decomposition of waste material. 
    • Decay in simple terms is the process in which the dead and waste material produced by plants and animals is eaten up by microorganisms. 
    • During this process, there is a breakdown of certain complex organic compounds by bacteria, viruses, etc., into simpler inorganic compounds present in those waste materials. 
    • This process is also referred to as rotting.  

    Decay or decomposition is important because it helps to provide inorganic material to the soil and clears out waste from the environment.
