Answer:
cadaverine
Step-by-step explanation:
Cadaverine is a chemical compound with the IUPAC name of pentane-1,5-diamine. It is a chemical compound that emits a foul odour when decomposers like bacteria act on dead animal tissues.
Cadaverine is a product of protein hydrolysis by bacteria in dead tissues, specifically when amino acid LYSINE is decarboxylated. Hence, cadaverine is the compound responsible for the terrible smell produced when a dead animal is being decomposed.
