Question

Organism have two intermediate host to complete its life cycle called

Answer 1

Terrestrial snail and ant are two intermediate hosts on which the human liver fluke depends on to complete its life cycle so as to facilitate parasitization of its primary host.

Answer 2

In biology and medicine, a host is an organism that harbours a parasitic, a mutualistic, or a commensalist guest (symbiont), the guest typically being provided with nourishment and shelter.

Examples include animals playing host to parasitic worms (e.g. nematodes), cells harbouring pathogenic (disease-causing) viruses, a bean plant hosting mutualistic (helpful) nitrogen-fixing bacteria.

• More specifically in botany, a host plant supplies food resources to micropredators, which have an evolutionarily stable relationship with their hosts similar to ectoparasitism.

• The host range is the collection of hosts that an organism can use as a partner.
