Here's why:
* Heterotrophs: These are organisms that cannot produce their own food and must obtain it from other organisms. This includes all animals, fungi, and most bacteria.
* Herbivores: These are animals that primarily eat plants. Vegetarians fall into this category.
* Other herbivores: There are many herbivores besides humans, such as cows, deer, rabbits, and many insects. They all get their energy solely from plants.
Therefore, the statement that vegetarians are the only heterotrophs getting all their energy from plants is incorrect.
