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.
