Which of the following example demonstrates the same type of relationship?

• Moths lay eggs in the seedpods of the yucca plant, the larvae hatch and feed on some but not all of the seeds and the moth acts as a pollinator for the plant.

• The goby fish and blind shrimp live in a tunnel in the sand created by the shrimp and when a predator is near the goby fish will touch the shrimp to warn it.

• Tapeworms live in the digestive system and eat partially digested food which eventually deprives the host of food and nourishment

• A Pseudoscorpion is a tiny scorpion with no stinger that moves from place to place by hitching a ride on much larger insects
