Undigested food may also be expelled this way, in a process called " egestion ".
2.
If you define digestion to be any combination of " ingestion, breakdown, absorption, and egestion, " then fiber could be included in digestion.
3.
In some species, there are pores in the pharynx opening to the ventral surface; these contain valves and may allow egestion of any excess water swallowed while feeding.
4.
Due to non-predatory death, egestion, and respiration, a significant amount of energy is lost to the environment instead of being absorbed for production by consumers.
