Organisms that depend on dead and decaying organic matter are called saprophytes. They play a crucial role in the ecosystem by breaking down dead organisms and recycling their nutrients back into the soil. This process is known as decomposition.

Importance of Saprophytes:
Saprophytes are important for the following reasons:

1. Nutrient recycling: Saprophytes break down dead organic matter and release nutrients back into the soil, which can then be used by other organisms.

2. Disease prevention: Saprophytes break down dead plant and animal matter, which helps to prevent the spread of diseases.

3. Detoxification: Some saprophytes are capable of breaking down toxins and pollutants, thus helping to detoxify the environment.

4. Soil formation: The decomposition of dead organic matter by saprophytes contributes to the formation of soil.

Examples of Saprophytes:
Some examples of saprophytes include fungi, bacteria, and some types of insects. Fungi are particularly important saprophytes, as they are responsible for breaking down the tough cell walls of dead plant material. Bacteria are also important saprophytes, as they are able to break down a wide variety of organic compounds.

Conclusion:
In conclusion, saprophytes are an essential part of the ecosystem, as they are responsible for breaking down dead organic matter and recycling its nutrients back into the soil. Without saprophytes, the ecosystem would be unable to function properly, and nutrient cycling would come to a halt.

Saprophytes are the animals which feed on dead and decaying animals. For example, moulds, mushroom etc
