Bacteria Kingdom
The Bacteria Kingdom, also known as Monera, consists of single-celled microorganisms that lack a nucleus. These organisms are incredibly diverse and can be found in various environments, from soil and water to the human body. Bacteria play essential roles in ecosystems, including nutrient cycling and decomposition.
Bacteria can be classified into two main groups: Eubacteria, which are common and include many familiar species, and Archaebacteria, which often thrive in extreme conditions. Some bacteria are beneficial, aiding in digestion and producing antibiotics, while others can cause diseases. Understanding bacteria is crucial for fields like medicine and environmental science.
