Explanation

**Step-by-Step Solution:**

1. **Understanding the Five Kingdom Classification**: The five kingdom classification system was proposed by the scientist Robert Whittaker. It categorizes all living organisms into five distinct kingdoms: Monera, Protista, Fungi, Plantae, and Animalia.

2. **Identifying the Characteristics of Each Kingdom**:
- **Monera**: This kingdom includes all prokaryotic organisms, primarily bacteria. Prokaryotes are characterized by the absence of a true nucleus and membrane-bound organelles.
- **Protista**: This kingdom consists of eukaryotic organisms that are mostly unicellular or simple multicellular organisms.
- **Fungi**: This kingdom includes eukaryotic organisms that are primarily multicellular (except for yeasts) and are heterotrophic.
