Leeches are organisms that live in ponds. They feed on the blood of fish and other vertebrates and produce enzymes, which cause the animal on which it feeds to continue bleeding even after the leech is done feeding. This relationship would be classified as which of the following?

• Freshwater producer/consumer
• Marine predator/prey
• Freshwater parasite/host
• Terrestrial parasite/host

Which of the following describes a predator/prey relationship in a marine environment?
