Question

Decomposes break down a dead tree is a physical or chemical change

Answer 1

Decomposition of a dead tree involves both physical and chemical changes. Initially, physical changes occur as the tree breaks down due to physical processes such as the wind blowing branches off or animals physically breaking apart the wood. However, the majority of the decomposition process involves chemical changes, where complex organic compounds in the tree are broken down into simpler substances through various chemical reactions, such as decay caused by fungi or bacteria.
