		Bacteria put the tang in yogurt and the sour in sourdough bread; bacteria help to break down dead organic matter; bacteria make up the base of the food web in many environments.
		Bacteria are of such immense importance because of their extreme flexibility, capacity for rapid growth and reproduction, and great age - the oldest fossils known, nearly 3.5 billion years old, are fossils of bacteria-like organisms.

		Although countless kinds of bacteria are found throughout the sea, they occur in the greatest concentration at the surface and at the bottom, with the mid-waters having the lowest concentration.
		Oceanic bacteria are extremely important insofar as they reduce dead matter to water-soluble materials which serve as basic food materials for the sea plants, which in turn form the food basis for marine animals.
		The filtering bacteria in the gravel of marine aquariums are mostly of the genera Nistrosomonas and Nitrobacter.

	B003 What are Bacteria?
		Many bacteria which cause diseases in hydra, snakes, turtles, and other cold-blooded animals, are not able to cause disease in birds or mammals because the high body temperatures kill these bacteria or limit their growth.
		Actually, it is usually bacteria in their guts that eat the wood and the animal lives on the dead bacteria and substances they produce.
		Bacteria are good subjects for studying the basic laws of inheritance because they grow rapidly and and have traits which are easily studied.

	Decomposition: Bacteria
		Some bacteria are autotrophic, making their own food in a similar way to plants by splitting carbon dioxide using energy from the sun, or through the oxidation of elements such as nitrogen and sulphur.
		Bacteria involved in the decomposition of animal bodies are heterotrophic, breaking down complex molecules into their constituent elements through respiration or fermentation (depending on whether they are aerobic or anaerobic bacteria).
		Bacteria are largely responsible for the recycling of carbon, nitrogen and sulphur into forms where they can be taken up by plants.
