Bacteria reproduces asexually which basically means it divides and both halves are exact replicas, Grasshoppers copulate end to end and lay eggs that they do not care for. Fish have numerous different way depending on the species but usually the female will find a suitable spot and lay her eggs and a male will come and fertilize them if she allows him too, usually their is an acceptance but no copulation. Bears being mammals reproduce by the female accepting a mate among a group of fighters and usually accepts the strongest one for his dominate genes. The male mounts the female from behind and inseminates her. She then carries the fetus's to term and the babies are born live.
