انسان+economical
شىء+economic

Sorry to say that your answer is not right. Economic is used before a noun to refer somehow to economy e.g economic problem means a problem with the economy etc but economical means not using a lot of money, fuel etc e.g The central heating is economical to run.She is very economical with the wrapping paper, isn't she? She cut it without an inch to spare. 1
