Question
Chapter 38.5, Problem 2MC
Summary Introduction
To analyze: The reason that some monarchs along the Gulf Coast stopped migrating and why this makes them prone to parasitic infections.
Introduction: The vivid orange, black, and white patterns on monarch butterflies make them stand out among other enormous, gorgeously colorful butterflies. The vibrant color of a monarch gives a signal to predators: Eat me not because I am poisonous. The only food source for the butterflies, while they are in the caterpillar stage, is milkweed, which is where the butterflies acquire their toxins from.

- It is not always easy to categorize a particular case of symbiosis.Suppose a certain species of snail is always found living on a certain coral. No one has found evidence that the snail harms the coral, so the relationship is classified as an example of commensalism. How would you go about testing this hypothesis?
