6. Which statement about seagulls and sea stars is true?
Natali5045456 [20]

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! :)
