Help with biology question ?

many fertilizers contain phosphorus to help plants grow. deposits of high phosphorus material come from the droppings of bats in caves and migrating BIRDS (hint!) on small islands piling up for thousands of years. farms in the chesapeake bay region spread their own high phosphorous manure. where did they get this kind of manure from ? (hint: think perdue!)
