Answer 2

Answer:

Option d - Grasshopper

Explanation:

• The mosquito is an external parasite.
• Cuscuta species is also known as dodders. These are plant parasites that connect to the vasculature of the host plant. They extract water, macromolecules and nutrients.
• Ascaris: It is an intestinal parasite that lives in humans. The most common worm infection is caused by Ascaris. The larvae and adult worms live in the small intestine. They cause intestinal disease.
• Grasshopper: It is a host, not a parasite. The behaviour of the host is influenced by the parasite. The parasite that lives in grasshopper is horsehair worms(Spinochordodes tellinii). Once the parasite is fully grown, it instigates the grasshopper to jump into the water, due to which the grasshopper drowns and dies.      

Hence, a grasshopper is a host but not a parasite.
