   Cyanobacteria such as these carry out photosynthesis.Their emergence foreshadowed the evolution of many photosynthetic plants and oxygenated Earth's atmosphere.. Biological carbon fixation, or сarbon assimilation, is the process by which living organisms convert inorganic carbon (particularly carbon dioxide, CO 2) to organic compounds.

   Commercially it can be known as Cetomacrogol 1000, Brij 58 (when n=20), Brij 56 (when n=10), and other trade names. It is used as a solubilizer and emulsifying agent in foods, cosmetics, and pharmaceuticals, often as an ointment base. [1] It is used as an oil in water (O/W) emulsifier for creams/lotions, and a wetting agent.

6. Ecological efficiency - Wikipedia

   en.wikipedia.org/wiki/Ecological_efficiency

   Ecological efficiency is a combination of several related efficiencies that describe resource utilization and the extent to which resources are converted into biomass. [ 1 ] Exploitation efficiency is the amount of food ingested divided by the amount of prey production ( I n / P n − 1 {\displaystyle I_{n}/P_{n-1}} )

7. Ecosystem ecology - Wikipedia

   en.wikipedia.org/wiki/Ecosystem_ecology

   Ecosystem ecology is philosophically and historically rooted in terrestrial ecology. The ecosystem concept has evolved rapidly during the last 100 years with important ideas developed by Frederic Clements, a botanist who argued for specific definitions of ecosystems and that physiological processes were responsible for their development and persistence.
