1. Bacteria: This domain includes organisms that are prokaryotic, meaning they lack a nucleus and other membrane-bound organelles. Bacteria are found in a wide range of environments, from soil and water to inside the human body. They play important roles in various ecological processes, such as nutrient cycling and decomposition.
2. Archaea: Archaea are also prokaryotic organisms, but they are distinct from bacteria in terms of their genetic makeup and biochemistry. Archaea are known for their ability to thrive in extreme environments, such as acidic hot springs and deep-sea hydrothermal vents. Some archaea are also important in biotechnology and bioremediation.
3. Eukarya: This domain includes all organisms that have eukaryotic cells, which are characterized by a membrane-bound nucleus and other organelles. Eukarya includes a wide range of organisms, from single-celled protists to multicellular plants, animals, and fungi. Eukaryotic organisms are found in virtually all environments on Earth and play diverse roles in ecosystems.
