There isn't a single, universally accepted term for organisms that are vegetarian. This is because "vegetarian" is typically used to describe a *diet* choice made by humans, not a characteristic of organisms in the natural world.

However, depending on the specific context, you could use terms like:

* Herbivores: This is the most common and accurate term for animals that primarily consume plants.

* Phytophagous: This scientific term refers to organisms that feed on plants.

* Plant-eating: This is a simple and straightforward description.

It's important to note that the terms "herbivore" and "phytophagous" are not always interchangeable. Some herbivores may also consume small amounts of animal matter, while some phytophagous organisms might be parasitic and live within plants, not just consuming them.

Therefore, the best term to use depends on the specific context and the level of detail you require.
