Organisms live in the soil surface, sub-surfaces, and even in the depths of the earth at the highest temperature. Organisms living in the soil in detail. Living organisms – earthworms, beetles, fungi, bacteria. Among the soil organisms that are pests of crops are nematodes, slugs and snails, symphylids, beetle larvae, fly larvae, caterpillars, and root aphids. The soil food web is the community of organisms living all or part of their lives in the soil. 11.13 Soil Organisms and Plant Damage 512.
