31. N . punctiforme are autotrophic cyanobacteria capable of fixing nitrogen and provides G . pyriforme with fixed nitrogen. 32. The Chromophyta ( Bourrelly, 1968 ) included the current Ochrophyta ( autotrophic Stramenopiles ), Haptophyta and Choanoflagellida. 33. Carboxysomes are bacterial microcompartments found in many autotrophic bacteria such as Cyanobacteria, Knallgasbacteria, Nitroso-and Nitrobacteria. 34. Ammonia oxidation in autotrophic nitrification is a complex process that requires several enzymes, proteins and presence of oxygen. 35. The term metabolosome is used to refer to such catabolic BMCs ( in contrast to the autotrophic carboxysome ). 36. Most ecosystems are supported by the autotrophic primary production of plants that capture photons initially released by the sun. 37. Most methanogens are autotrophic producers, but those that oxidize CH 3 COO " are classed as chemotroph instead. 38. The autotrophic nature of anammox bacteria and ammonia-oxidizing bacteria guarantee a low yield and thus less sludge production. 39. Because ecologically, autotrophic organisms precede heterotrophs, it seems natural to assume that evolutionarily this must also be so. 40. In ferns the gametophyte is a small flattened autotrophic prothallus on which the young sporophyte is briefly dependent for its nutrition.
