Give you an example of a paratism?

Answer 1

one organism is helped the other is harmed, ex: tick drinks your blood, you get less blood.

The bot fly and the human being.

Only the bot fly larvae live as parasites. Dermatobia hominis, the human botfly, is the only species of botfly known to use humans as the host to its larvae.

Another example of parasitism is fleas and mammals.

parasites that live on the hosts surface are called ectoparasites (e.g. fleas and some mites)

parasites that live inside the host are called endoparasites (e.g. tape worms or the protozoan of the genus Plasmodium, that causes malaria).
