Protists which break down organic material are known as fungus-like protists. A few examples of this type of protist are water molds and slime molds.

Fungus-like protists
When living material undergoes decomposition, organic matter forms as the organic compounds within the material break down into simpler molecules. This process is driven by the activity of decomposers such as bacteria, fungi, and other organisms that break down complex organic compounds into humus, which is a key component of organic matter in soil.
Fungi are the group of organisms that are all absorptive in their nutrition. They break down organic matter externally and absorb the nutrients. This is in contrast to plants that perform photosynthesis and animals that ingest food.
Fungal-like protists, such as slime molds, function similarly to fungi in that they secrete digestive enzymes to break down organic matter in their surroundings. Once the enzymes break down the food, the protists absorb the nutrients through their cell membranes for energy and growth. This process is essential for their survival and reproduction.
Enzymes such as amylase, cellulase, and protease can break down organic matter found in mud. These enzymes help to degrade starches, cellulose, and proteins, respectively, facilitating the decomposition of organic material in mud.
They break down a lot of fresh organic material into compost, or rich soil.
Fungi
Detritivores consume and break down dead organic matter, while decomposers primarily break down organic matter into simpler substances through chemical processes. Detritivores physically consume the material, while decomposers chemically break it down. Both play important roles in the decomposition process.
Decaying organic matter refers to plant or animal material that is in the process of breaking down and decomposing. This process is carried out by microorganisms like bacteria and fungi, which feed on the organic material and break it down into simpler substances. Decaying organic matter plays a critical role in nutrient cycling and soil fertility in ecosystems.
The majority of mineral nutrients and organic material is found in the topsoil layer of soil. Topsoil is typically rich in nutrients and organic matter due to the presence of decomposing plant and animal material, as well as microbial activity that helps break down organic matter into nutrients.
Yes, some protists are decomposers. Protists like amoebas, ciliates, and flagellates play a role in breaking down organic matter in the environment, contributing to the decomposition process.
