A) Mineralization involves organisms; decomposition is a purely chemical process.
B) Decomposition involves organisms; mineralization is a purely chemical process.
C) Mineralization breaks down detritus into smaller parts; decomposition breaks down organic compounds into inorganic nutrients.
D) Decomposition breaks down detritus into smaller parts; mineralization breaks down organic compounds into inorganic nutrients.
E) Mineralization occurs in the geological portions of the cycle; decomposition occurs in the biological portions.

The key distinguishing factor between mineralization and decomposition is that mineralization breaks down organic compounds into inorganic nutrients (such as nitrogen, phosphorus, and carbon), while decomposition breaks down detritus (dead organic matter) into smaller parts. Both processes involve the breakdown of organic matter by microorganisms, but the end products are different. Mineralization is an important part of nutrient cycling in ecosystems, as it releases nutrients that plants can use for growth.
