The correct answer is +/-.
There are different types of interactions and relationships between the various species of an ecosystem. If both species benefit from an interaction, then we talk about a mutualistic interaction which is symbolized by +/+. There are competitive interactions where both of the species are affected negatively and are symbolized as -/-. In this example, while the lion pride is benefited by the interaction, the African wild dog is excluded from specific areas of the ecosystem and therefore the species is disadvantaged. This relationship is symbolized as +/-.

Answer:
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:

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.
