Ecology

Gopher tortoises create their homes by digging holes in wee drained sandy soils throughout the southeast region of the U.S. The florida pine snakes will sometimes share the hole with the tortoises to shelter from weather or fire. 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
