Question 10 refers to the following alternatives: INTERACTION 1: Early summer flowers such as Trillium spp., are pollinated by a variety of flies, and bees. In exchange for providing pollination services, the insects receive nectar and pollen to eat themselves and to feed their young. INTERACTION 2: Parrotfish are predators of marine invertebrates, including crustaceans, bivalves, and other reef fauna. INTERACTION 3: Human eyelashes have at least two different species of eyelash mites. These mites feed off of dead skin cells, and obtain a sheltered habitat from us. They do not affect our ability to survive and reproduce. INTERACTION 4: Humans all over the world harbor worms that live in their bloodstream and other structures. These worms use their human host as a staging area to release their eggs into the environment, and weaken their host, often shortening his or her lifespan. INTERACTION 5: Several species of Bethylid wasps oviposit into crickets. Their larvae eat the crickets and emerge adults. They then mate and disperse to find new hosts. INTERACTION 6: The desert tortoise shares a burrow with the sidewinder rattlesnake. The snake, unable to dig a burrow of its own, gets a place to sleep during the day. The tortoise gets a venomous snake to guard its burrow. 10. Which is an example of parasitism? A) Interaction 4 B) Interaction 2 C) Interaction 3 D) Interactions 3 and 4 E) None of the above
