Why does a predator kill its prey but a parasite rarely kill its host?
Usually, parasites are much smaller than the host is, whereas predators could be either small or larger than the prey. Parasites have a very high reproduction rate but the predators reproduce slowly.

Do you protozoan that are parasites never have more than one host?
Protozoan parasites can have one or multiple hosts throughout their life cycle. Some species, like Plasmodium (which causes malaria), require different hosts, including mosquitoes and humans, to complete their development. Other protozoan parasites may only need a single host to thrive and reproduce. Therefore, it is not accurate to say that parasitic protozoa never have more than one host.
How are viruses similar to parasites?
Viruses are similar to parasites because both require a host to survive and both destroy the cells in which they multiply (cause harm to the host).
What types of parasites reproduce only in living cells other than viruses?
Parasites that reproduce only in living cells, apart from viruses, include certain types of protozoa, such as Plasmodium species (which cause malaria) and Leishmania species. Additionally, some intracellular bacteria, like Chlamydia and Rickettsia, must replicate within host cells. These organisms rely on the host's cellular machinery for their reproduction and survival, making them obligate intracellular parasites.
Are parasites usually smaller than the host?
Yes
Do parasites ever have more than one host?
FALSE!
What is the definition of overfishing?
Fishing faster than the fish can reproduce.
Why are hosts often not killed in parasitic relationships?
Hosts are often not killed in parasitic relationships because it is in the parasite's best interest to keep the host alive for as long as possible to continue providing nutrients and resources. If the host dies too quickly, the parasite may not have enough time to reproduce and spread to other hosts. Additionally, killing the host too quickly may alert the host's immune system, leading to the parasite being eliminated.
Why are elephants are getting less in number?
We are killing them faster than they can reproduce.
Why would it be bad for the parasites if it killed the plant or animal it lives on?
Because it would deprive itself of its food-source. Parasites thrive by feeding off a 'host' - rather than catching their own food. If they kill off the host - they either have to find another host - or die !
