Question

What challenges do you think parasites face in their survival? how can these challenges affect the parasite? .com?

Answer 1

Answer:

        Parasites as well as any other organism, need to fullfill their needs of survivability.

Explanation:

        These needs include having enough energy to survive and pass its genes to the next generation. For that to happen, its life cycle needs to be complete, and for that, the organism the parasite is in cannot die, and that can be a very hard task, once the parasite does not have the knowledge about that, and in lots of times, it kills the organism he infected, dying with it right after because its needs are not going to be fulfilled anymore.

         There are several different kinds of parasites, each of them having different life cycles, those can be very hard or easy to accomplish. Another challenge can be the body defenses, that means, chemical reactions could be created by the body to protect itself, killing the parasite.

Answer 2

Parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. Some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. Ectoparasites live outside the body of the host, and can more easily disperse, but are more exposed to predators, parasites, parasitoids. Endoparasites live inside the body of the host, and are therefore protected from the outside environment. But they can be attacked by the host's immune system. They have therefore developed mechanisms for dispersal such as complex life cycles.
