What 2 hosts do a parasite need?

A parasite typically requires two hosts: the definitive host and the intermediate host. The definitive host is where the parasite reaches maturity and reproduces, while the intermediate host is where the parasite undergoes development or larval stages. This two-host life cycle allows the parasite to complete its life cycle and spread effectively. Examples include the malaria parasite, which uses humans as the definitive host and mosquitoes as the intermediate host.
