Observe the given diagram representing global biodiversity and answer the question.

Identify which is not represented in the figure?

Bacteria

The correct answer is Option (3) → Bacteria

The correct answer is Bacteria because bacteria are typically not represented in traditional ecological pyramids or food chain diagrams not represented in diagrams that show global biodiversity proportions for major taxa of plants, invertebrates, and vertebrates. Global Biodiversity Representation Diagrams illustrating global biodiversity usually focus on visible, multicellular organisms, such as plants (e.g., mosses like Funaria and Sphagnum), invertebrates (like crabs and prawns), and unicellular algae (e.g., Chlamydomonas). These groups have well-documented species that are easier to categorize in terms of biodiversity.
