Eubacteria autotroph or heterotroph
13.1.10 kingdom eubacteria
This “junk drawer” kingdom includes slime molds and protozoans, which means it comprises a wide range of organisms! Autotrophs, heterotrophs, unicellular, and multicellular organisms are all possible. Both protests have a nucleus and are eukaryotes. Protozoans are protists that live in fresh water.
Organisms are classified into seven levels.
These levels are described in order of increasing specificity. The further traits and classification schemes that species have in common, the more they have in common.
Archaebacteria and eubacteria are the two kingdoms of bacteria. Both kingdoms share characteristics such as being prokaryotes (organelles without membranes) and being unicellular. Bacteria are heterotrophic and autotrophic in different ways. Chemo synthesis is the ability of certain archaebacteria and eubacteria to perform photosynthesis or even use chemicals as a source of nutrients. Some bacteria are autotrophic, meaning they produce their own food through photosynthesis or chemosynthesis, while others are heterotrophic, meaning they obtain nutrients from their surroundings. Eubacteria and Archaebacteria have free-flowing DNA in the cytoplasm since they are prokaryotes and lack membrane-bound organelles like a nucleus. They lack organelles such as mitochondria and endoplasmic reticulum. Bacteria are essential in more ways than you would think; they aid in the recovery of nutrients from decomposing organic matter. They also aid in the digestion of several species. Autotrophic bacteria, such as purple bacteria, rely on photosynthesis for food. Most bacteria, however, are heterotrophic, meaning they feed on other species. Bacillus anthracis, which causes anthrax, is one of the most dangerous bacteria. Cyanobacteria, on the other hand, aid in the production of vast quantities of oxygen for the planet. Bacteria can be found almost anywhere, but most bacteria prefer warm environments. Archaebacteria, on the other hand, can survive in extreme environments such as the ocean’s depths. Selector for Pages
Kingdom monera [five kingdom classification] | structure
The Earth is home to a diverse range of life forms. Life has taken on many wonderful forms and evolved countless survival mechanisms, ranging from single-celled organisms to creatures with trillions of cells. Remember that all living organisms are made up of one or more cells, according to cell theory. Unicellular species are those that are made up of just one cell. Multicellular organisms are those that have more than one cell. Despite the diversity of species, only two basic cell plans exist: prokaryotic and eukaryotic. The key distinction between these two cell types is that eukaryotic cells have organelles, which are internal membrane-bound structures (see chp 2.3). Thus, depending on the form of organism, microscopically analyzing the cells of every organism on Earth will reveal either prokaryotic or eukaryotic cells.

Cells are categorized based on their basic structural units and how they receive energy. Prokaryotes and eukaryotes are the two types of cells, which will be discussed further in the next two pages of this tutorial.
Based on form, living things are divided into six kingdoms. The kingdoms Monera (Eubacteria) and Archaea are found within prokaryotes, which first appeared 3.5 billion years ago. Protista, Plantae, Fungae, and Animalia are kingdoms within eukaryotes, which evolved 1.5 billion years ago. “Self feeders” that use light or chemical energy to make food. Autotrophic organisms include plants. Heterotrophs (“other feeders”), on the other hand, get their nutrition from other autotrophs or heterotrophs. Heterotrophs include a wide range of bacteria and animals.
Multicellular organisms are made up of a complex network of interconnected cells. New mechanisms for cell-to-cell communication and regulation are needed. There must also be distinct pathways for a single fertilized egg to expand into all of the body’s various tissues.
