Detailed explanation-1: -In a parasitic relationship, one organism benefits at the expense of another. For example, mosquitoes drink human blood, which causes humans to get itchy and can even get them sick.

Detailed explanation-2: -Malaria parasites are transmitted to human hosts by female mosquitoes of the genus Anopheles. A diverse group of Anopheles (30 to 40 species) serves as vectors of human disease. Several physiological, behavioral, and ecological characteristics determine how effective various Anophelesspecies are as vectors of malaria.

Detailed explanation-3: -The organisms that parasitize humans include fungi, leeches, lice, viruses, protozoa, tapeworm, etc. Few organisms such as Helminthes live inside the intestine of the host and causes several infectious diseases, such as jaundice, malnutrition, diarrhoea, etc. All the infections are caused by viruses and bacteria.

Detailed explanation-4: -parasitism, relationship between two species of plants or animals in which one benefits at the expense of the other, sometimes without killing the host organism.
