Do you ever wonder what type of bacteria causes those tooth decays, turn milk into yougurt, or gives you food poisoning? Your answer is Eubacteria. Eubacteria is the second group of Monereans and make up there own kingdom. Eubacteria are bacteria that are uncellular and are prokaryotes. They are single celled organisms. This bacteria lives in variety of habitats and they also obtain there energy variety differents ways. The phylums of this Kingdom are organized by the way the bacteria obtains energy.
One of the main phyla is the heterotrophs. In this phyla the type of bacteria that is found is almost everywhere. These type of bacteria needs organic molecules as an energy source. Even though they need organic molecules as an energy source, the bacteria can't consume food that contain this type of molecules. what the bacteria in this phyla does is survive on other species by living as parasites or saprobes. The second phyla of the Eubacteria Kingdom is the autotrophs. The Autotrophs is bacteria that is photosynthetic. An autotroph is an organism that can make there own food. the way that they make there own food is through photosynthesis, which uses the suns energy to make the sugar molecules. Tis bacteria is commonly found with a blue-green color. This is why sometimes that bacteria is also called blue-green bacteria. This bacteria is composed out of chains of bacteria cells. this is an exeption to the rule that monerans are unicellular. The chains that connect the bacteria also show an existing of chlorophyll which it helps provide evidence that bacteria could be the ancestors for plants. Third butnot last is the phyla called chemotrophs. The bacteria that exist in this phyla is a bacteria that obtain there energy from chemosynthetic breakdown of inorganic substances. Some examples would be like sulfur and nitrogen compounds. The importance of this bacteria is that it converts nitrogen in the atmosphere to forms that can be used in plants.
