Write a short note on parasites
Answers
Answer:
A parasite is an organism that lives in another organism, called the host, and often harms it. It depends on its host for survival. Without a host, a parasite cannot live, grow and multiply. ... Parasites, unlike predators, are usually much smaller than their host and they reproduce at a faster rate.
A parasite is an organism that lives within or on a host. The host is another organism.
The parasite uses the host’s resources to fuel its life cycle. It uses the host’s resources to maintain itself.
Parasites vary widely. Around 70 percent are not visible to the human eye, such as the malarial parasite, but some worm parasites can reach over 30 meters in length.
Parasites are not a disease, but they can spread diseases. Different parasites have different effects.
Endoparasite : These live inside the host. They include heartworm, tapeworm, and flatworms
Epiparasite : These feed on other parasites in a relationship known as hyperparasitism.
There are three main types of parasites.
Protozoa: Examples include the single-celled organism known as Plasmodium. A protozoa can only multiply, or divide, within the host.
Helminths: These are worm parasites. Schistosomiasis is caused by a helminth. Other examples include roundworm, pinworm, trichina spiralis, tapeworm, and fluke.
Ectoparasites: These live on, rather than in their hosts. They include lice and fleas.
