Final answer:
Rapid burial helps prevent decomposition of dead organisms, leading to better preservation and potential fossilization.
Step-by-step explanation:
Rapid burial of a dead organism helps to preserve it from being destroyed through decomposition. Decomposition is a natural process in which organic substances are broken down into simpler organic matter. The rapid burial of an organism in an oxygen-free, low-energy sedimentary environment can prevent bacterial decay, leading to the preservation of soft tissues which are typically challenging to maintain. Such conditions are rare, making fossilization a rather exceptional occurrence. Other forms of preservation include freezing in glaciers or encapsulation in tree resin, which can also help prevent decomposition.
