Here's why:
* Plantae (plants) are autotrophs, meaning they can produce their own food through photosynthesis. They use sunlight, water, and carbon dioxide to create sugars (energy) for growth.
* Animalia (animals) are heterotrophs, meaning they must consume other organisms for energy.
* Fungi are also heterotrophs, obtaining nutrients by absorbing organic matter from their surroundings.
* Protista is a diverse kingdom, but it includes both autotrophs and heterotrophs.
