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.
