List Product

Define a predicate list_prod/2 that takes a list of numbers as a first parameter and determines the product of all of the list elements in the second parameter. Your predicate should have the signature list_prod(+List, +Number). The product of an empty list should be zero. Examples: ?- list_prod([4,3], Product). Product = 12. ?- list_prod([7,8,0,13], Product). Product = 0. ?- list_prod([6,2,5,10], Product). Product = 600. ?- list_prod([], Product). Product = 0.

Please answer in Prolog
