Before long, says lee frelich of the university of minnesota’s center for forest ecology, “earthworms become the dominant living thing that influences the ecosystem they influence the type of plants that can grow, the type of insects that can live there, the habitat. Earthworm ecology earthworms can play a variety of important roles in ecosystems their feeding and burrowing activities incorporate organic residues and amendments into the soil, enhancing decomposition, humus formation, nutrient cycling, and soil structural development (mackay and kladivko, 1985 kladivko et al, 1986. Earthworms are dependent on moderate soil moisture content, and cultivation tends to have a negative effect on earthworms by decreasing soil moisture (zicsi, 1969) some common agricultural lumbricids are allolobophora chlorotica , the aporrectodea caliginosa species complex (a trapezoides, a turgida, and a tuberculata), and l terrestris.
