Understand the classification system: The domain Eukarya includes all organisms with eukaryotic cells, which have a nucleus and membrane-bound organelles. This domain is distinct from the domains Bacteria and Archaea, which consist of prokaryotic organisms.
Review the groups within the domain Eukarya: The major groups (or kingdoms) within Eukarya include Fungi, Plantae, Animalia, and Protista. These groups are characterized by their cellular structure and modes of nutrition.
Analyze the options provided: Cyanobacteria and Bacteria belong to the domain Bacteria, while Archaea belongs to the domain Archaea. These are prokaryotic domains and not part of Eukarya.
Identify the correct group: Fungi is a kingdom within the domain Eukarya. Fungi are eukaryotic organisms that include yeasts, molds, and mushrooms, and they obtain nutrients through absorption.
Conclude the reasoning: Since Fungi is the only group listed that belongs to the domain Eukarya, it is the correct answer.
