What are members of a large kingdom of organisms that live as decomposers?

Members of a large kingdom of organisms that live as decomposers are primarily fungi and certain bacteria. These organisms play a crucial role in ecosystems by breaking down dead organic matter, recycling nutrients back into the soil, and facilitating plant growth. Fungi, such as mushrooms and molds, secrete enzymes to digest complex organic materials, while bacteria contribute by decomposing simpler compounds. Together, they help maintain ecological balance and support the nutrient cycle.
