1. What is the host for parasitoids wasps?
2. Why is it important for us to study parasites—host relationships?
3. Describe what a predator prey relationship is and provide an example.
4. Describe what a parasite-host relationship is and provide an example.
5. There are numerous relationships in an oceanic ecosystem. Provide examples of the following relationships:
- Predator-Prey
-Parasite- Host
-Consumer-Consumer
-Consumer- Producer

1. Many parasitoid wasps use larval Lepidoptera as hosts, but some groups parasitize different host life stages (egg, larva or nymph, pupa, adult) of nearly all other orders of insects, especially Coleoptera, Diptera, Hemiptera and other Hymenoptera.

2. These interactions may be synergistic or antagonistic and therefore produce diverse effects in infected humans and animals. Interactions among parasites strongly influence parasite dynamics and therefore play a major role in structuring parasite populations (both within and among hosts) as well as host populations.

3. A predator is an organism that eats another organism. The prey is the organism which the predator eats. Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit. Predator and prey evolve together.

4. A parasitic relationship is one in which one organism, the parasite, lives off of another organism, the host, harming it and possibly causing death. The parasite lives on or in the body of the host. A few examples of parasites are tapeworms, fleas, and barnacles.

5. predator-prey: Seastars prey on mussels and shellfish which would otherwise have no other natural predators.

parasite-host: nematodes, leeches, and barnacles.

consumer-consumer: ?

consumer-producer: fish eating algae?

Explanation:

(hope this is enough)

answer///(c) the maximum number of organisms an environment can support for a long time; i believe this is correct, plz check luck;
