Question

how can we say that mushroom derive nutrion from DECAYING matter because something becomes decaying when bacteria fungi or mushroom act upon them then this should be said that they feed on dead matter but when that mushroom is feeding upon it ,it decays

Answer 1

Mushroom cannot synthesize its own food as it lacks chlorophyll. Mushroom obtains its nutrition from decaying matter because in decaying matter organic nutrients are found in abundance. Mushroom absorbs the required organic nutrients directly through the cell membrane from the decaying matter. This type of nutrtion is called saprotrophic nutrition.
