Decomposers

Matter is reused in the ecosystem

producers, consumers, and decomposers cycle matter as they consume food and die, returning nutrients to the soil to be used by plants to grow.

Decomposers break down materials in an ecosystem and release organic compounds to be used by plants.

Composting

  • Compost is produced when gardeners make a mixture of various decaying organic substances, such as dead leaves or kitchen scraps, and allow the mixture to decay naturally. The compost is then used for fertilizing the soil.
