How long does it take an apple to decompose and why?

An Apple typically takes about 1 to 3 months to decompose, depending on environmental conditions such as temperature, humidity, and the presence of microorganisms. In warmer, moist environments, decomposition occurs more rapidly due to increased microbial activity. Factors like exposure to air and the Apple's condition (e.g., whether it's whole or has bruises) also influence the rate of decomposition.
