| Bacteria present in organic matter can have adverse effects on human and animal health. |
| The most common is activated sludge, a process in which microbes, also known as biomass, are allowed to feed on organic matter in the wastewater. |
| Additionally, carbon dioxide and organic acids may be added to the water from the soil, where they form by decay of organic matter. |
| The weathered minerals of the regolith, together with an admixture of organic matter and water, make up the soil. |
