Explanation:

• Bacteria: Bacteria are single - celled organisms. Some bacteria are pathogenic (e.g., Salmonella which causes food poisoning), while some are edible. For example, certain types of bacteria are used in the production of fermented foods like yogurt (Lactobacillus).
• Viruses: Viruses are not considered single - celled organisms. They are acellular entities that require a host cell to replicate.
• Protozoa: While protozoa are single - celled, they are not typically known for being edible. Protozoa are more often associated with causing diseases (e.g., Plasmodium which causes malaria) or being part of aquatic ecosystems.
