2025 Biological ClassificationFive Kingdom Classification Medium Question 1 of 5 in Five Kingdom Classification

Each of the following characteristics represent a Kingdom proposed by Whittaker. Arrange the following in increasing order of complexity of body organization.
A. Multicellular heterotrophs with cell wall made of chitin.
B. Heterotrophs with tissue/organ/organ system level of body organization.
C. Prokaryotes with cell wall made of polysaccharides and amino acids.
D. Eukaryotic autotrophs with tissue/organ level of body organization.
E. Eukaryotes with cellular body organization.
Choose the correct answer from the options given below:

A A, C, E, B, D
B C, E, A, D, B
C A, C, E, D, B
D C, E, A, B, D

The answer is B.

Solution

Order of complexity: Monera (C) -> Protista (E) -> Fungi (A) -> Plantae (D) -> Animalia (B).

In Whittaker's five-kingdom classification, organization complexity increases from: C (Monera, unicellular prokaryote) \rightarrow E (Protista, unicellular eukaryote) \rightarrow A (Fungi, multicellular loose mycelium) \rightarrow D (Plantae, tissue/organ autotrophs) \rightarrow B (Animalia, tissue/organ/organ-system heterotrophs).
