Nettet1. mar. 2006 · Plant debris decomposes in the soil, releasing carbon dioxide. This is because bacteria and fungi break down dead leaves by the following chemical reaction: C x (H 2 O) y + x O 2 → x CO 2 + y H 2 O + energy. This reaction is one of the components of the global carbon cycle. Different types of plant material decompose at different rates.
