While it might seem surprising, both organisms use sunlight to produce energy.
* Rabbits are heterotrophs, meaning they get their energy from consuming other organisms (like grass). However, some bacteria in their gut are able to perform photosynthesis.
* Grass plants are autotrophs, meaning they produce their own energy through photosynthesis. They use sunlight to convert carbon dioxide and water into sugar for energy.
