Which kingdom includes organisms that are primarily decomposers?

The kingdom that includes organisms primarily functioning as decomposers is Fungi. Fungi play a crucial ecological role by breaking down dead organic matter, which recycles nutrients back into the ecosystem. They have specialized structures, such as hyphae and mycelium, which allow them to efficiently absorb nutrients from their surroundings. This decomposition process is vital for soil health and fertility, promoting the growth of plants and maintaining the balance of ecosystems.

In contrast, Monera primarily consists of prokaryotic organisms, including bacteria, which can also play a role in decomposition but are not exclusively classified as decomposers. Plantae includes organisms that primarily produce energy through photosynthesis and do not function as decomposers. Animalia consists of heterotrophic organisms that consume other organisms for energy, rather than breaking down organic matter as their primary function.
