What is a host in a parasitic relationship?

• A host is the organism that is harmed or used by the parasite for its benefit.

• A host is the organism that benefits from the relationship with the parasite.

• A host is an organism that lives independently without any relationship.

• A host is a type of parasite that feeds on other organisms.

What is parasitism?

• A type of mutualistic relationship where both organisms benefit.

• A type of symbiotic relationship where one organism benefits at the expense of the other.

• A relationship where organisms compete for the same resources.

• A type of commensalism where one organism is unaffected.

Why are symbiotic relationships important in ecosystems?

• They help in the reproduction of plants only.

• They contribute to the balance and health of ecosystems by facilitating interactions among species.

• They are only beneficial for one species involved.

• They have no significant impact on the ecosystem.
