For example, nitrifying bacteria use energy released in the oxidation of ammonia to nitrate and reduce CO. to organic carbon of carbohydrate. On a global basis, the amount of organic matter synthesized by chemoautotrophy is very small in comparison with the quantity produced by photosynthesis.

Application of these techniques can enhance soil condition and water quality, improve production efficiency, and prolong the useful life of ponds.

Below the thin, aerobic surface layer where oxygen is the terminal electron acceptor in respiration are successive layers where nitrate, iron and manganese, sulfate, and carbon dioxide, respectively, are used as electron acceptors or oxidants in respiration. Fermentation also occurs in anaerobic soil.

Most ponds are built from and in soil. Many dissolved and suspended substances in water are derived from contact with soil. Pond bottom soils are the

Watershed ponds are formed by making embarkments across natural watercourses to impound runoff. Soils for building embankments may come from both insi

Most vascular plants absorb carbon dioxide through their leaves and take in water and mineral nutrients through their roots. The root system extends into the soil and provides a large surface area for absorbing nutrients and water

Photosynthesis is a well-known reduction reaction; inorganic carbon in carbon dioxide is reduced to organic carbon in carbohydrate with the capture of energy. Aerobic respiration is an oxidation reaction in which carbon in org
