What is a decomposer in the sierra Nevada alpine?

In the Sierra Nevada alpine ecosystem, decomposers play a crucial role in nutrient cycling by breaking down organic matter, such as dead plants and animals. Common decomposers in this region include fungi, bacteria, and certain invertebrates like earthworms and insects. By decomposing organic material, they release nutrients back into the soil, promoting plant growth and maintaining the health of the alpine ecosystem. Their activity is especially important in the harsh alpine conditions, where nutrient availability can be limited.
