The cell cycle is the replication of reproduction of cells, whether in eukaryotes or prokaryotes. It is important to organisms in many different ways, but overall it allows them to survive.

Answer:
Low Enzyme Production is the reason for no breaking down of food.
Explanation:
If the digestion of food did not occur so it means that there is low enzyme production because enzymes are responsible for the breaking down of food substances into simpler ones in order to absorb by the cells for the generation of energy in the form of ATP. So we can conclude that low enzyme production is the only reason for the stopping of breaking down or digestion of food.
