Question

Starting with the European settiers, humans have introduced earthworms from Europe and Asia into North American forests. These introductions continue through the

transport of soil that contains non-native earthworms, such as during construction and through the release of non-native earthworms used for fishing. The effects of
non-native earthworms are especially large in forests that did not have any native earthworms. For example, forests of the Great Lakes region did not previously have
earthworms until humans introduced them. When non-native earthworms are introduced, the thick layer of leaves, known as leaf litter, covering the ground disappears
quickly, thereby altering biogeochemical cycies.
What is a possible beneficial consequence of introducing the earthworms to forests in the Great Lake regions?
A.The earthworm increases the energy fow from one tropic level to the next.
B.The earthworms provide competition for other native, primary consumers
C.The eanthworms burrow, which improves the nutrients, fow of air, and water underground
D.The earthworms are secondary consumers that provide another food source for tertlary consumers.

Answer 1

c

because earth worm barrow land hence improve

soil aeration, drainage and also decompose dead

organic matter thus increasing soil nutrients
