1) The human liver fluke, a nematode parasite, depends on two intermediate hosts (a snail and a fish) to complete its life cycle.
2) The malarial parasite needs a vector (mosquito) to spread to other host organisms.
3) In case of brood parasitism, the eggs of parasitic birds (e.g., cuckoo) are not detected and removed from the nest because the parasite's eggs resemble the host's eggs in morphology and colour.
4) A population of frogs protected from all predators would decrease indefinitely.
