The Hidden Life of Soil: Exploring Its Vibrant Microbial Community

Soil is teeming with life, hosting billions of organisms that play critical roles in ecosystems. From the microscopic bacteria and fungi to larger organisms like earthworms and slugs, these creatures contribute to decomposition, nutrient recycling, and soil aeration. This diverse community includes nematodes, protozoa, and mites, each with unique functions. Explore the fascinating biology of soil, discover the interconnectedness of these organisms, and understand their importance for healthy ecosystems and agriculture.

  13. Vocabulary • Decompose (Decomposition) • Fungus (plural Fungi) • Microbes • Microbiologist • Organisms

  14. Vocabulary • Bacteria -Single-celled organisms that are microscopic ranging in shape from spheres, rods, to spirals. • Earthworms -Long, thin segmented animals that burl through the soil aerating and enriching it. • Mites -Eight-legged animals too small to see with the unaided eye that feed on smaller organisms and soil organic matter. • Nematodes -Tiny, non-segmented worm-like organisms that mostly live on other organisms or soil organic matter. • Protozoa -Single-celled organisms larger than bacteria that move in water films and feed on bacteria and soil organic matter. • Rotifers-Microscopic animals found in many freshwater environments and in moist soil that move by swimming or crawling. • Springtails -Six-legged animals that often have a tail-like structure folded beneath the body that can be used for jumping when the animal is threatened.
