Decomposition

Decomposition is the process of dead things breaking down into simpler materials. Bacteria, fungi, worms, and insects all help break down dead plants and animals. This process puts nutrients back into the soil. Without decomposition, dead things would pile up everywhere.

Nature's Recyclers

Decomposers are living things that break down dead matter. Mushrooms and other fungi are important decomposers. Bacteria are the smallest decomposers but do the most work. Worms, beetles, and other small creatures also help by chewing dead material into smaller pieces.

Why Decomposition Matters

Decomposition returns nutrients to the soil so new plants can grow. It is like nature's recycling system. Without decomposers, soil would run out of nutrients. Composting is a way people use decomposition to turn food scraps into rich soil for gardens.

Fun Facts

• A fallen log in the forest can take 50 to 100 years to fully decompose.
• There are more bacteria in one teaspoon of soil than there are people on Earth.
• Mushrooms are the visible part of fungi that do most of their decomposing work underground.

Did You Know?

Without decomposers, the world would be buried under piles of dead leaves, fallen trees, and animal remains! Decomposers recycle about 90 percent of all dead material in nature.
