Detailed explanation-1: -All fungi are heterotrophic, which means they are unable to synthesize their own food (like plants), so they must consume organic matter as food. Some of the species of fungi are parasitic, but most fungi are decomposers, which means they break down dead and decaying material and use that as a source of nutrition.

Detailed explanation-2: -It became very difficult to group some living things into one or the other, so early in the past century the two kingdoms were expanded into five kingdoms: Protista (the single-celled eukaryotes); Fungi (fungus and related organisms); Plantae (the plants); Animalia (the animals); Monera (the prokaryotes).

Detailed explanation-3: -Humans belong to the Kingdom Animalia. Organisms belonging to kingdom Animalia are multicellular, eukaryotic and heterotrophic. Humans, further, belong to the Class-Mammalia, Order-Primates, Family-Hominidae, Genus-Homo and species-sapiens.

Detailed explanation-4: -Kingdom Archaebacteria consist of prokaryotic organisms. These organisms are all unicellular and their cells do not have a nucleus or complex organelles. The prefix Archae means ancient. The organisms in this kingdom are believed to be similar to the first types of living organisms found on the Earth.
