Nedbrytare, or decomposers, are organisms that break down dead organic matter, returning essential nutrients to the soil. They play a crucial role in ecosystems by recycling nutrients, which supports plant growth and maintains soil health. Common examples of nedbrytare include bacteria, fungi, and certain insects. These organisms thrive in various environments, from forests to oceans, and are vital for the decomposition process. By breaking down complex organic materials, nedbrytare help to create a balanced ecosystem, ensuring that energy flows through food webs. Their activity is essential for sustaining life on Earth, including plants and animals.
