Detailed explanation-1: -Usually, although parasites harm their hosts, it is in the parasite’s best interest not to kill the host, because it relies on the host’s body and body functions, such as digestion or blood circulation, to live.
Detailed explanation-2: -Many parasites, however, must kill their hosts to achieve transmission, and in these contexts selection by definition favours maximal virulence.
Detailed explanation-3: -Parasites generally do not kill the host but may harm the host indirectly by spreading pathogens. This may affect the host’s behaviour, metabolism or its reproductive activity. Many parasites have hooks, claws or suckers to attach to their host.
Detailed explanation-4: -Parasites are organisms that live in or on a living host of another species. They survive by taking nutrients from this host.
