Question

Endoparasites:

Select one:
a. Iive inside a host
b. usually do not harm their hosts, especially the definitive host
c. often change hosts and reproduce in a definitive host
d. sometimes change the behaviour of an intermediate host, making it more vulnerable to being eaten by a definitive host
e. all of the above

Answer 1

Endoparasites are organisms that live inside a host and may cause various degrees of harm. They typically refrain from killing the host rapidly to ensure their reproductive cycle is completed, and can manipulate an intermediate host's behavior to facilitate transmission to a definitive host. The correct answer is e. all of the above.

Step-by-step explanation:

Understanding Endoparasites

Endoparasites are organisms that live inside a host, often causing harm by deriving nutrients needed for their survival. Contrary to ectoparasites, which live on the external surface of the host, endoparasites such as hookworms, tapeworms, and roundworms inhabit the inside of their host's body. While parasites in general do benefit at the expense of the host, they typically do not kill the host swiftly, as this would jeopardize their reproductive cycle which often relies on the host for transmission to additional hosts. In cases involving a definitive host, parasites aim to complete their lifecycle and may even cause behavioral changes in an intermediate host to increase their chances of transmission to the definitive host.

So, the correct answer to the question is e. all of the above, as endoparasites do indeed live inside a host, they do not usually harm their definitive hosts substantially, they often change hosts in complex lifecycles, and they can manipulate the behavior of an intermediate host to become more vulnerable to predation by a definitive host.
