Question

Quizplus · Accepted Answer

Cyanobacteria have several competitive advantages in aquatic environments, including the ability of many species to fix nitrogen, which provides a source of this essential nutrient limited in many aquatic systems. Cyanobacteria also have the ability to produce toxins to resist predation, which can limit the growth of other organisms and provide a competitive advantage. In addition, some cyanobacteria produce hydroxamates, which can chelate iron and provide a source of this nutrient in environments where it is limiting. Therefore, all of the choices (A, B, and C) contribute to the competitive advantages of cyanobacteria in aquatic environments.
