Challenges faced by parasites in their quest to inhabit a biotic environment

Parasitists have to the body's immune system to establish parasitism, in addition to having to deal with the damage it does to the host organism.

Explanation:

Parasites are organisms that associate with living beings in an unequal relationship, where the parasite uses the vital resources of living beings for their survival, generating problems for the host organism.

As biotic environments where parasites can grow, we can mention plants and animals. For parasitism to be established, the parasite must face the immune defense system of these organisms, in addition to having to face the evils that are caused by parasitism, since the parasite needs the host to be alive for it to survive.
