Exploring the Bacteria Kingdoms

The video explains that infections are often caused by bacteria, microscopic organisms without a nucleus. Bacteria can either consume other organisms or use sunlight to produce food. They are classified into two kingdoms: Eubacteria and Archaebacteria. Archaebacteria thrive in extreme environments like hot springs and hydrothermal vents, where they generate energy from environmental chemicals.
