geophagia การใช้

It remains unknown which function is the more important in avian geophagia.
However, geophagia has become less prevalent as rural Americans assimilate into urban culture.
In the southern United States in the 1800s, geophagia was a common practice among the slave population.
Geophagia is nearly universal around the world in tribal and traditional rural societies ( although apparently it has not been documented in Japan and Korea ).
Larger organisms may also consume soil ( geophagia ) or use mineral resources, such as salt licks, to obtain limited minerals unavailable through other dietary sources.
