If all the meiofaunal organisms were eliminated from a sandy beach, how would that affect the habitat and the trophic structure of the beach?
What will be an ideal response?
Meiofaunal organisms are an important link between microscopic bacteria, rotifers and other small infaunal organisms. The meiofauna eat these small organisms and, in turn, are eaten by larger predators. Without meiofauna, the secondary production of these microscopic infauna would be lost to the trophic system of the sandy beach, and the beach wouldn't be able to support many larger consumers.
