WebGCSE AQA Biology Foundation Biology Higher Revise Topic Specification Decomposition Plant and animal waste is broken down by microorganisms called decomposers to release energy in a process called decay or decomposition. Humans take advantage of this process to make compost and biogas. WebBeta Decay Because 14 C is radioactive, it decays over time–in other words, older artifacts have less 14 C than younger ones. 14 C decays by a process called beta decay. During this process, an atom of 14 C decays into an atom of 14 N, during which one of the neutrons in the carbon atom becomes a proton.
