Parasites live in or on another organism, which is called the host. When the eggs hatch, its larvae burrows into the ant’s body and starts feeding on it from inside, eventually killing it. Sometimes, the parasite species will even kick the other species’ eggs out of the nest, forcing the host to raise only the parasite’s young. Facultative parasites do not rely on the host in order to complete their life cycle; they can survive without the host, and only sometimes perform parasitic activities. The host fish can still eat, and will survive with an isopod in its mouth, but the isopod consumes a small amount of the fish’s blood and mucus while living there. 2. a.

Well, we're looking for good writers who want to spread the word. Microparasites are too small to be seen and must be viewed under a microscope. Digenetic parasites need more than one host to complete their life cycle. This occurs commonly in wasps such as Ampulex compressa, whose young eat paralyzed cockroaches that have been stung by the parent. This means that they usually will not cause serious harm to the host, as the parasites need the host to survive so that they can survive, unless the host’s death is needed for the transmission of the parasite. You must have also seen fungi species on tree trunks in the wild, or around your house for that matter. Example: Plasmodium (malarial parasite) in female Anopheles mosquito.
