What can bacteria do with “broken down” materials ?

Answers

Bacteria have the ability to break down dead organisms into smaller particles and create new compounds. We use decomposers to restore the natural nutrient cycle through controlled composting. Bacteria secreting enzymes out of their cells into the soil or dead organism. The enzymes digest the organic material. When they break down organic material, they give off heat. Billions of aerobic bacteria working to decompose the organic matter in a compost pile causes the pile to warm up. As the temperature rises, different organisms thrive.
