Explanation:

Parasitism is a relationship where one organism (the parasite) benefits at the expense of another (the host). Flesh - eating bacteria harm the human skin (the host) while benefiting themselves. In contrast, the other options are examples of mutualism (where both organisms benefit). For instance, wood - processing protozoa in termite gut help termites digest wood and get food in return; decomposing fungi around plant roots help plants get nutrients and get organic matter to decompose; Escherichia coli in human gut can help with digestion (in some cases) and get a habitat and nutrients.

Answer:

Flesh - eating bacteria on human skin.
