Biotic activity (BA)

[German version]

	Zero order biotic activity: Nonliving products, products exhibiting passive behavior
	1st order biotic activity: Living organisms with fully maintained intrinsic metabolism, in which anabolic metabolic processes predominate, e.g. livestock (domestic and zoo animals) and poultry. Anabolic and catabolic metabolic processes must be kept at least in equilibrium by appropriate feeding and care.
	2nd order biotic activity: Living organs, such as fruit (bananas, citrus fruits, pomaceous fruit), vegetables (tomatoes, sweet peppers, potatoes, onions), grains, legumes, oil-bearing seeds/fruits, in which respiration process (= external respiration) predominate, because their supply of new nutrients has been cut off by separation from the parent plant.
	3rd order biotic activity: Goods in which respiration processes (external respiration) are suspended, but in which biochemical, microbial and other decomposition processes still proceed, such as meat, fish, processed grain products, dried fruits, spices, cocoa and coffee beans, tea, tobacco, expellers, fish meal. Such goods are not provided with hermetically sealed packaging.
	4th order biotic activity: Goods in which biochemical and microbial processes have stopped and which are isolated from the external environment, e.g. sterilized and pasteurized goods in hermetically sealed packaging (preserved foods, beverages).
