Here's a breakdown:

* Parasite: An organism that lives in or on another organism (the host) and benefits by deriving nutrients at the host's expense.

* Hyperparasite: An organism that lives in or on another parasite and benefits by deriving nutrients at the parasite's expense.

Examples of hyperparasites:

* Certain fungi that infect insects parasitizing plants.

* Wasps that lay their eggs inside the larvae of other parasitic wasps.

* Bacteria that infect parasitic nematodes (roundworms).

Hyperparasitism can be a complex ecological relationship with important implications for the control of parasites. For example, hyperparasites can sometimes be used to help manage harmful parasites in agricultural settings.
