Fact of the Day: 31/01/2023

Most people have probably seen decomposition. When you look at the back of your fridge and see an old, bruised, discolored apple sitting there, the apple has most likely started decomposition. How does the process work? It involves the cooperation of various creatures. If decomposition occurs in the great outdoors, the first step takes place in the soil, where, according to Utah State University, “earthworms and other soil animals break [an organic product] . . . into smaller pieces in a process called fragmentation. This is an important step, because smaller fragments have more surface area to support the growth of bacteria and fungi” (par. 3). Rain can further help the process by dissolving the materials and carrying away chemicals that were released. Small organisms, such as fungi and bacteria, then incorporate the decaying matter into the soil by growing on the dead matter, digesting it, and turning it back into nutrients.

Decomposition can be seen during the fall time as the leaves change color due to the chemical reactions and then slowly disintegrate in the soil once they fall. The rate at which materials decompose may change depending on the exact conditions, but the main process is the same. Decomposition is so interesting, involving chemicals and fungi. It’s really so much more than just your food going bad!
