soil bacterium

Soil bacteria are tiny microorganisms that live in the ground, playing vital roles in the environment. They help decompose dead plants and animals, recycling nutrients back into the soil to support plant growth. Some bacteria form beneficial relationships with plants, aiding in nutrient absorption. Others can break down pollutants or fix nitrogen, making the soil more fertile. These bacteria are essential for healthy ecosystems, agriculture, and maintaining the balance of nature underground. Despite their small size, soil bacteria have a big impact on life above ground by fostering healthy, productive soils.
