Question

which of the following is an example of parasitism?
select the correct answer.
a bear stalking a deer
a flea biting a dog
squirrels fighting over acorns
a frog eating an insect

Explanation:

Parasitism is a symbiotic relationship where one organism (the parasite) benefits at the expense of another (the host). A flea biting a dog fits this as the flea (parasite) gets food (blood) while harming the dog (host). A bear stalking a deer and a frog eating an insect are examples of predation. Squirrels fighting over acorns is competition.

Answer:

a flea biting a dog
