Answer:
B. Sea stars are the prey of seagulls
Explanation:
Seagulls eat sea stars, meaning that sea stars are their prey (the organism that is eaten).
Predator: an organism that eats (preys on) another organism
Prey: an organism that is eaten by another organism (creatures can be both predator and prey. For example, a rabbit is a predator to grass, while they are prey to foxes)
Host: An organism that is fed on by a parasite. Think of a dog with a tick. The dog is the host, the tick is the parasite.
Incorrect answers (and why):
A. Sea stars do not eat seagulls
C. If a sea star was a predator to a seagull, that would mean that they eat seagulls. They do not.
D. A host is an organism that a parasite preys on. Not only are sea stars not parasites, but they definitely do not prey on seagulls.
I hope this helps! :)
