bio-, bi-, -bia, -bial, -bian, -bion, -biont, -bius, -biosis, -bium, -biotic, -biotical

(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.

1. Produced by the activity of living organisms.
2. That part of biology that seeks to account for the resemblances and the differences in organisms related by descent.

It is the science that simply studies in living organisms such genetic phenomena as heredity and evolution, development and variation; whereas the doctrinal movement that tries to anticipate or enforce the practical utilization of the scientific principles studied is eugenics.

Produced by a living organism or resulting from the actions of living organisms; such as, fermentation, necessary for life processes, including food and water.
biogenic theory
The theory that fossil fuels represent the altered remains of ancient plant and animal life deposited in sedimentary rocks, and therefore have a biological origin.

Generally accepted in preference to the abiogenic theory that hydrocarbon deposits became part of the earth as it formed.

1. Originating from life or producing life.
2. Living on or in other organisms.
A reference to the science dealing with the relationship between the geochemistry of a given region and its flora and fauna, including the circulation of such elements as carbon and nitrogen between the environment and the cells of living organisms.
biogeochemical cycle (s) (noun), biogeochemical cycles (pl)
1. The circulation of chemical components through the biosphere from, or to, the lithosphere, atmosphere, and hydrosphere.
2. The exchange of elements; for example, oxygen, carbon, nitrogen, etc., in the environment between storage pools; such as, the atmosphere, biota, oceans, soils, the earth's crust, and human society.
1. The branch of biochemistry that deals with the relation of chemicals found in the soil to living organisms; the biological application of geochemistry.
2. The study of the influence of living organisms and life processes on the chemical structure and history of the earth.
3. The study of interactions between the biosphere and its mineral environment; for example, the study of the effect of living organisms on the weathering of rocks and of the concentration of elements by living systems.
4. The branch of science that studies the biological, chemical, and geological aspects of environmental processes.
biogeocoenology, biogeocenology
The study of ecosystems.
The science of the geographical distribution of living things; such as, animals and vegetation.
biogeographer (s) (noun), biogeographers (pl)
1. A specialist in biogeography or someone who studies the distributions of living things; such as, plant and animal life in the earth's environment and the biological and historical factors that produced such distributions.
2 .Scientists who study the spacial distributions of individual organisms in biotic communities which are composed of plants and animals and of ecosystems, or environmental systems, which are associations of biotic communities interacting with their environments.

An ecosystem may be defined and studied at sizes in areas ranging from a small pond to a global biome; such as, prairies or tropical rain forests.

A reference to the science of the geographical distribution of living things, animal and vegetable.
biogeographic regions
Regions of the world containing recognizably distinct and characteristic endemic fauna or flora.
Referring to the study of the geographic distribution of plants and animals.
