- An obligate parasite, or holoparasite, is a parasitic organism that cannot complete its life-cycle without exploiting a suitable host. If an obligate parasite cannot obtain a host it will fail to reproduce.

- A parasite is an organism that lives on or in a host organism and gets its food from or at the expense of its host. There are three main classes of parasites that can cause disease in humans: protozoa, helminths, and ectoparasites.

Malaria Malaria is an infection caused by single-celled parasites that enter the blood through the bite of an Anopheles mosquito. These parasites, called plasmodia, belong to at least five species. Most human infections are caused by either Plasmodium falciparum or Plasmodium vivax.

- Obligate aerobes are organisms that need oxygen for their survival and multiplication example plants, animals, and fungi. Not all microbes are obligate aerobes; some have the ability to survive in the absence of oxygen.

10 why are viruses called obligate intracellular parasites? They are called obligate intracellular parasites because they must use a host cell's amino acids to synthesize proteins, metabolic enzymes and pathways to obtain energy, ribos … omes to synthesize proteins, and nucleotides for transcription and replication.hey are obligate in the sense that they cannot replicate outside of a host cell. To make a copy of itself, a virus must first enter a cell (intracellular), hijack the machi … nations of said cell (parasitic behavior) and then copy itself. 24 people found this useful.

-   Aut … otrophs are organisms which can make their own organic substances from inorganic materials eg water and carbon dioxide. Plants are autotrophs.   Amoeba proteus is a free-living heterotroph, which feeds on other microscopic organisms such as ciliates and algae.rganisms that are consumers or decomposers are  heterotrophs. A parasite is also a heterotroph. A parasite feeds  off other organisms for its food. An example of a parasite is a  deet tick. An example of a decomposing heterotroph is an earthworm.  An earthworm decomposes biological matter in soil for its food.

Obligate parasite Obligate parasite. An obligate parasite or holoparasite, is a parasitic organism that cannot complete its life-cycle without exploiting a suitable host. If an obligate parasite cannot obtain a host it will fail to reproduce. This is opposed to a facultative parasite, which can act as a parasite but does not rely on its host to continue its life-cycle. Obligate parasites have evolved a variety of parasitic strategies to exploit their hosts.

Facultative parasite From Wikipedia, the free encyclopedia. A facultative parasite is an organism that may resort to parasitic activity, but does not absolutely rely on any host for completion of its life cycle. Examples of facultative parasitism occur among many species of fungi, such as family members of the genus Armillaria.

Intracellular parasite Obligate intracellular parasites cannot reproduce outside their host cell, meaning that the parasite's reproduction is entirely reliant on intracellular resources.

Facultative parasite An example of this in humans is Naegleria fowleri. As a rule this amoeboid species is a free-living predator on microbes, but occasionally it successfully infects humans as a facultative internal parasite.

- Ichthyophthirius Multifilis is an obligate parasite. This means that it can only live in the presence of fish. The actual visible white spots are the feeding stage, called a trophont. The trophont grows and then drops off the fish, falling to the bottom of the tank and forms a cyst called a tomont.

About Parasites On this Page. A parasite is an organism that lives on or in a host organism and gets its food from or at the expense of its host. There are three main classes of parasites that can cause disease in humans: protozoa, helminths, and ectoparasites. Protozoa are microscopic, one-celled organisms that can be free-living or parasitic in nature.

- Plasmodium, commonly known as the malaria parasite, is a large genus of parasitic protozoa. As with some other genera of clinically important microorganisms, the genus name also yields a common noun; thus species of the genus are known as plasmodia.nfection with plasmodia is known as malaria, a deadly disease widespread in the tropics. The parasite always has two hosts in its life cycle: a mosquito vector and a vertebrate host. The life-cycle is very complex, involving a sequence of different stages both in the vector and the host.
