*”Zoology #36 Symbiosis: Parasitism” Quiz with Answers *
1. What kind of relationship is there between the two species
in parasitism?
The type where only ONE species is helped, and the other one IS harmed.
2. What do you call the organism that’s hurt in a parasitic
relationship?
The harmed organism is called the host.
3. True or False: puppies are parasites.
False! Puppies aren’t harmful in any relationships they might have (well,
except maybe for picking up puppy poop).
4. Are viruses, like COVID and the flu, parasites?
ALL viruses are parasitic, so colds, flu, and COVID are all a form of
parasitism.
5. What parasite is the only one to replace an organ of its
host?
The tiny aquatic isopod known as the tongue-eating louse (*Cymothoa exigua*
).
6. What does a tongue-eating louse eat (besides the tongue!)?
It feeds off the fish’s blood, mucus (yum), and even some of what the fish
is eating.
7. What is a parasitoid?
Parasitoids are insects whose larvae live as parasites inside the host,
usually another insect, and who eventually kill the host.
8. What’s a jewel wasp’s 1st sting do?
This venom temporarily paralyzes the front legs of the roach, then the rest
of the roach as it spreads.
9. What does the second sting do?
It paralyzes the parts of the brain that control the roach’s escape reflex,
so it calms down and doesn’t try to get away once it can move again.
10. What does a jewel wasp do with a cockroach’s antennae?
First, it chews off half of each of them and eats the blood that oozes out.
Then it grabs hold of a chewed-off antenna and uses it like a leash,
leading & pulling the roach to its burrow – like taking Oreo for a walk!
