What is another name for microbes?

Microbes are a diverse group of microscopic organisms that include not just bacteria, but also a variety of other life forms such as viruses, fungi, and parasites. The term "microbes" is often used interchangeably with "microorganisms," which encompasses all types of these small organisms, including bacteria.

Bacteria are one of the primary types of microbes and are characterized by their single-celled structure. They play essential roles in various ecosystems, human health, and biotechnology, contributing to processes like digestion and fermentation. While the other options refer to specific categories of microbes — viruses, parasites, and fungi — the term "microbes" most broadly and inclusively captures bacteria as a significant and fundamental subset of microorganisms. Thus, relating this choice specifically to the broader classification of microbes makes it the most fitting response.
