The correct option is
D Ectoparasitism
The correct option is D.
Explanation for correct option:
- When a parasite lives in the body of the host then it is referred to as ectoparasitism.
- Here the host-parasite relationship remains non-mutual.
- Cuscuta is a stem parasite that wraps around the host plants and remains attached to them.
- It is an example of ectoparasitism and in this type of parasitism the dependent organism or the parasite is dependent on the host for its food.
Explanation for incorrect option:
Option A:
- Brood parasitism is generally seen in birds.
- Some species of birds lay their eggs in the nest of their host and then the host incubates them.
Option B:
- Predation refers to the common feeding behavior of living beings where one species feed on another to survive.
- It is not parasitism.
Option C:
- In endo parasitism, the parasite lives in the tissues and organs of its hosts.
- But as Cuscuta lives outside the host body then it is not an endoparasite.
Final answer: Cuscuta is an example of ectoparasitism.
