(Greek: life; living, live, alive)

Don’t confuse this element with another bi- which means "two".

The most important things in life are not things.

The deliberate use by humans of one species of organism to eliminate or to control another one, as in the control of undesirable plants or insects by the use of natural parasites, diseases, or predators, rather than by herbicides and pesticides.

A well known example of the use of natural predators, rather than industrial pesticides, may be seen in the case of beetles ("lady bugs") especially selected to control aphids that infest wheat and other grain crops.

1. The microbial conversion of a chemical into a compound of economic importance, or the conversion of organic material into a source of energy, using biological processes or organisms.
2. Any of various processes that use plants or micro-organisms to change one form of energy into another form; such as, the fermentation of carbohydrates into alcohol; the digestion of organic wastes, or sewage, with micro-organisms to produce methane.
3. The conversion of biomass into usable energy; such as, by burning solid fuel for heat, by fermenting plant matter to produce liquid fuel, as ethanol, or by the bacterial decomposition of organic waste to produce methane.
Corrosion caused by, or enhanced by, bacteria or other microorganisms; resulting in biologically induced corrosion.
A bureaucrat representing the interests of the biological sciences or environmental protection.
A crude oil similar to petroleum which can be produced from biomass under high pressure and temperature.

It can then be treated with hydrogen to upgrade it to a transportation fuel for use in place of conventional diesel fuels.

biocyberneticist, biocybernetician (s) (noun); biocyberneticists, biocyberneticians (pl)
Someone who applies mathematical theory to the communication and control of living organisms: A biocyberneticist obtains or provides physiological feedback mechanisms and central nervous system controls, including the brain, spinal cord, nerves, and ganglia (the mass of nerve tissue existing outside the central nervous system).
biocybernetics (s) (noun) (a plural form used as a singular)
1. The science of communications and control in animals: The study of biocybernetics involves information about the physiological performance of the mechanisms and central nervous system controls and of the interactions between organisms and mechanical or electronic systems.
2. The science of communication and control within a living being; especially, on a molecular basis: Biocybernetics includes the processes of how communications and controls occur within the bodies of living systems between different parts of the body and of the interactions between organisms and mechanical or electronic systems.
1. One of the three main divisions of the biosphere: marine, freshwater, or terrestrial habitat.
2. The rhythmic repetition of certain phenomena observed in living organisms.
biodata, bio
Biographical details, especially those supplied by candidates applying for jobs; a résumé.
The quality of being readily digested or broken down chemically by organisms in the environment.
biodegradable (adjective)
1. Anything that is susceptible to the decomposing action of living organisms, especially of bacteria; which are occasionally broken down by biochemical processes in the body.
2. Denoting a substance that can be chemically degraded or decomposed by natural processes (for example: weather, soil bacteria, plants, animals) without harming the environment. Also, biodeterioration.
3. Describing organic compounds that are able to be decomposed by bacteria and other micro-organisms; such as, the constituents of sewage, as compared with non-biodegradable compounds; such as, most plastics.
biodegradation, biological degradation
1. The series of processes by which living systems render chemicals less noxious to the environment.
2. The breakdown of organic materials into simple chemicals by biochemical processes..
1. To decay and to become absorbed by the environment.
2. The conversion of molecules from one form to another within an organism, often associated with change in pharmacologic activity; refers especially to drugs and other xenobiotics.
3. The series of processes by which living systems render chemicals less noxious to the environment.

Also, biotransformation.

biodemography (s) (noun, biodemographies (pl)
The science dealing with the integration of ecology and the genetics of human populations: Biodemographies consist of information about birth and death processes as they relate to populations in general and to humans in particular.
biodestructable (adjective), more biodestructable, most biodestructable
Capable of being decomposed into harmless elements without danger to the environment.
