omnivory

This term is primarily used in biological and ecological contexts to describe a specific dietary strategy. It carries a neutral, scientific tone and is rarely used in casual conversation, where phrases like "eating everything" or "being an omnivore" are more common.

As an abstract noun denoting a biological characteristic or habit, it is uncountable. It does not have a plural form and cannot be used with a count modifier; one does not refer to "an omnivory" or "omnivories."
