Which insect is the host of the parasitic organism that causes sleeping sickness?
Host (biology) be reinfected several times. A host of predilection is the one preferred by a parasite. An amplifying host is one in which the level of pathogen can become high enough that a vector such as a mosquito that feeds on it will probably become infectious. A secondary or intermediate host harbors a parasite only for a short transition period, during which (usually) some developmental stage is completed. For trypanosomes, the cause of sleeping sickness, strictly, humans are the secondary host, while the tsetse fly is the primary host, given that it has been shown that reproduction occurs in the insect.
Parasitic nutrition Parasitic nutrition Parasitic nutrition is a mode of heterotrophic nutrition where a parasitic organism lives on the body surface or inside the body of another type of organism (a host) and gets nutrition directly from the body of the host. Since these parasites derive nourishment from their host, this symbiotic interaction is often harmful to the host. Parasites depend on their host for survival, since the host provides nutrition and protection. As a result of this dependence, parasites have considerable modifications to optimise parasitic nutrition and therefore their survival. In other words - Parasites are small organism which lives upon
