Here's why:
* Fungi are heterotrophic organisms, meaning they cannot produce their own food. Instead, they obtain nutrients by absorbing them from their surroundings. They do this by secreting enzymes that break down organic matter (like dead plants and animals) into simpler substances they can then absorb.
* Plants are autotrophic, meaning they produce their own food through photosynthesis.
* Animals are heterotrophic, but they obtain nutrients by ingesting food, unlike fungi who absorb it directly.
* Protists and Monera are diverse kingdoms with members that use a variety of methods to obtain nutrients, but absorption is not a defining characteristic.
