Yes, schistosomiasis has an intermediate host, which is typically a type of freshwater snail. The larvae of the Schistosoma parasites develop within these snails before being released into the water, where they can infect humans. The infection occurs when people come into contact with contaminated water, leading to the transmission of the disease.
No, schistosomiasis is not autotrophic. Schistosomiasis is caused by parasitic flatworms called schistosomes, which are heterotrophic organisms. They obtain their nutrients by feeding on the host's tissues and blood rather than producing their own food through photosynthesis or chemosynthesis, as autotrophic organisms do.

Schistosomiasis is a parasitic disease caused by blood flukes of the genus Schistosoma. It is commonly found in tropical and subtropical regions where freshwater snails serve as intermediate hosts for the parasite. People become infected with schistosomiasis through contact with contaminated water sources.

Intermediate host - snail definitive host - cattle/sheep
An intermediate host is an animal that is needed for a parasite to develop through one or more stages of life before being transferred to a definitive host in which the parasite will develop into sexual maturity. A reservoir host is a host that may be an intermediate or definitive host but provides a place where a parasite may "hang out" while enviromental conditions are less than optimal.

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.
Tapeworms are considered indirect parasites because they often require an intermediate host to complete their life cycle. Typically, the adult tapeworm resides in the intestines of a definitive host, such as a mammal, while its larval stages develop in intermediate hosts, like fish or livestock. Transmission occurs when the definitive host consumes the infected intermediate host.
