The organic component of a Garden World; includes all living organisms (whether natural or bionanites or both) and all organic matter that has not yet decomposed.
Biospheres occasionally develop naturally, but much more often result from the hand of terragen mindkind. In either process, the chemical reactions of life (e.g., photosynthesis-respiration, carbonate precipitation, etc.) impart a strong signal on the chemical composition of the atmosphere, transforming it from reducing conditions (e.g. EoGaian) and oxidizing environment with free oxygen. The biosphere is structured into a hierarchy known as the food chain whereby all life is dependent upon the autotrophs of the first tier. The biosphere can be divided into distinct ecosystems that represent the interactions between a group of organisms forming a trophic pyramid and the environment and the natural or artificial habitat in which they live.
Biospherics - Text by M. Alan Kazlev The study, design, construction, and maintenance, of artificial biospheres.
Ecological Classification Type - Text by M. Alan Kazlev Typology for a planet or biospheres's ecosystem, the biotic, virchlife, and nanecological counterpart of Planet Classification Type. Also useful in developing biological and mathematical models for preservation, terraforming, colonization, climate control, etc. The system of ecological classifications used today are based upon the classification scheme of the Banks Institute of Ecology (Negentropy Alliance).
Ecological Responsibility - Text by M. Alan Kazlev A major aspect of Bioism, this refers to the importance of preserving the health of one's biosphere, and especially of all natural garden worlds. In some memeticities (many forms of Zoeticism and Biosophism for example) biospheres are themselves considered living entities.
Ecopoiesis - Text by M. Alan Kazlev The science and art of designing, shaping, sculpting, or modifying ecosystems.
Ecosystem - Text by M. Alan Kazlev Community of organisms - whether biological or alife - interacting with one another and with the chemical and physical factors making up their environment.
Ecotourism - Text by M. Alan Kazlev Service industry built around tourism and leisure value of Garden Worlds and other ecologically sensitive areas. Ecotourist operators may often have to consider the needs of a local caretaker god or eco-protectionist clade.
