Which kingdom includes organisms that absorb food from their environment, such as yeasts and molds?

The correct choice is the kingdom Fungi, which comprises organisms that primarily obtain their nutrients through absorption. Fungi are unique among the kingdoms of life because they break down organic material in their environment using enzymes. This process occurs outside their cells, enabling them to absorb the resulting nutrients. This characteristic distinguishes them from other kingdoms such as Plantae, which produce their own food through photosynthesis, and Animalia, which typically ingest food. Additionally, while some members of Kingdom Protista may absorb nutrients, the defining feature of Fungi is their specialized mode of absorption and decomposition of organic material, as seen in organisms like yeasts and molds. These traits are central to their ecological role as decomposers in various ecosystems.
