kingdoms of life

The kingdoms of life categorize all living organisms into distinct groups based on shared characteristics. Traditionally, there are five main kingdoms: 1. **Monera**: Simple, single-celled organisms like bacteria. 2. **Protista**: Mostly single-celled organisms, such as algae and protozoa. 3. **Fungi**: Multicellular organisms like mushrooms and yeast that decompose organic matter. 4. **Plantae**: Multicellular plants that produce their own food through photosynthesis. 5. **Animalia**: Multicellular animals, including humans, that consume other organisms for energy. These classifications help scientists study and understand the diversity of life on Earth.
