Definitions
Century Dictionary and Cyclopedia
- n. In botany, an abnormal mode of obtaining nutrition, observed especially in the Cupuliferæ. These plants, according to Frank, are destitute of root-hairs, and depend for their nutrition upon a fungus, the mycelium of which closely surrounds the roots and acts in the capacity of root-hairs. In contradistinction to these are most ordinary plants, which obtain their nourishment by autotrophy—that is, by means of ordinary root-hairs. See
symbiosis .

“Approximately 200 budgets demonstrate the extreme heterogeneity of the coastal zone, with most of the variability towards both autotrophy and heterotrophy being in smaller systems.”
“The heterogeneity about a net metabolism near 0 is a more striking characteristic than a strong trend towards net autotrophy versus heterotrophy.”
