1. Imagine that you are traveling in Madagascar when you find the plant to the left. You see that the plant has an unusually large spur containing nectar in its tip. You remember learning in science class that some moths feed on nectar. Draw a picture of what you think a moth may look like that feeds on this plant. How might natural selection bring about the evolution of this orchid and the moth?

11. Mimicry is a type of commensalism that exists in nature. One organism evolves to look like the other in order to benefit itself. The mimic benefits from the situation while the organism it mimics in unaffected. Example: Example: Orchid flowers that mimic female wasps
