Final answer:
Examples of organisms from each of the six kingdoms include E. coli for Kingdom Bacteria, Methanogens for Kingdom Archaea, Amoeba for Kingdom Protista, Oak trees for Kingdom Plantae, Baker's yeast for Kingdom Fungi, and Lions for Kingdom Animalia.
A bear belongs to Kingdom Animalia.
Organisms within the same class also share the same phylum.
Step-by-step explanation:
Examples of Organisms in Each of the Six Kingdoms
In the current classification system, all living organisms are categorized into six kingdoms. Each kingdom represents a large group of organisms that share similar characteristics. Here are examples for each:
- Kingdom Bacteria: Escherichia coli (E. coli) - a common intestine-dwelling bacterium.
- Kingdom Archaea: Methanogens - microorganisms that produce methane.
- Kingdom Protista: Amoeba - a single-celled organism found in water or soil.
- Kingdom Plantae: Oak tree (Quercus species) - a common type of large tree.
- Kingdom Fungi: Saccharomyces cerevisiae (Baker's yeast) - used in baking and brewing.
- Kingdom Animalia: Panthera leo (Lion) - a large carnivorous mammal.
Classification of Specific Organisms
A bear is classified under Kingdom Animalia because bears are multicellular organismsthat get their energy through ingesting other organisms. An orchid, being a multicellular organism that gets its energy through photosynthesis, falls under Kingdom Plantae. The sea cucumber, like the bear, also belongs to Kingdom Animalia because it is a multicellular organism that ingests other organisms to obtain energy.
Consistency in Taxonomic Grouping
Organisms that belong to the same class must belong to the same phylum. In the Linnaean system of classification, taxa are arranged in a hierarchical structure that includes domain, kingdom, phylum, class, order, family, genus, and species, with domain being the highest level of classification and species being the most specific.
