Most successful parasites, such as a cat flea, weaken their host but do not kill it. Why is killing its host usually disadvantageous for a parasite? Question 4 options:

Relatives of the host would then attack the parasites.

Lysosomes from the host would then attack the parasite.

If a parasite kills its host, it will then have to find a new host in order to survive.

Parasitism is a relationship where both organisms benefit; killing the host is not beneficial to the host.
