How are living organisms currently categorized?
Living organisms are currently classified into three large groups called Domains. These domains are the archaea, bacteria, and eukaryote. Each of these domains are further broken down into kingdoms and within those kingdoms there are further subgroups.
Which kingdoms do not have photosynthetic organisms?
Some kingdoms that do not have photosynthetic organisms include Animalia, Fungi, and certain species within the Protista kingdom. These organisms obtain their energy through other means, such as consuming organic matter or absorbing nutrients from their environment.
What is a homogeneous subgroups?
Homogeneous subgroups are subsets within a larger group where the individuals or elements share similar characteristics or properties. These subgroups are internally consistent in terms of certain attributes or qualities. Identifying homogeneous subgroups can help in understanding patterns, behaviors, or dynamics within a population.
Species diversity is the number of?
species of all six kingdoms living within an ecosystem.

Why is it difficult to classify viruses into one of the 5 kingdoms of living organisms?
Viruses lack the characteristics of living organisms, such as cellular structure and metabolism, making it challenging to classify them within the traditional system of biological classification. Additionally, viruses are considered obligate intracellular parasites that can only replicate inside host cells, further complicating their classification within the existing kingdom system.
How do the kingdoms of living organisms differ?
Kingdoms and domains are used to classify living things. There are 3 domains: Bacteria, Archaea, and Eukaryote. Within the domains, living things are sorted into Kingdoms. There are currently 5 Kingdoms protista, bacteria, archaea, plants, animals, and fungi. Previously, only the 5 kingdom system existed. Later however, the domains were added.

Some kingdoms that do not have photosynthetic organisms include Animalia, Fungi, and certain species within the Protista kingdom. These organisms obtain their energy through other means, such as consuming organic matter or absorbing nutrients from their environment.

What are the similarities between the 6 kingdoms of life and the 3 domains of life?
The three domains of life (Bacteria, Archaea, Eukarya) represent the highest levels of classification, while the six kingdoms (Animalia, Plantae, Fungi, Protista, Archaea, Bacteria) are more specific groupings within these domains. Both systems categorize organisms based on shared characteristics and evolutionary relationships, with the domains focusing on fundamental differences in cellular structures and biochemistry, while the kingdoms further classify organisms based on shared traits and ecological roles.
What are some of the properties that are used to divide living things into kingdoms?
Living things are divided into kingdoms based on several key properties, including cell type (prokaryotic vs. eukaryotic), cellular organization (unicellular vs. multicellular), mode of nutrition (autotrophic vs. heterotrophic), and reproductive methods. For example, organisms in the plant kingdom are primarily autotrophic and multicellular, while those in the animal kingdom are typically multicellular and heterotrophic. Additionally, genetic and evolutionary relationships are considered to classify organisms within these kingdoms.
What traits do scientist use to classify living things into kingdoms?
Scientists use several traits to classify living things into kingdoms, including cell type (prokaryotic vs. eukaryotic), cell structure, mode of nutrition (autotroph vs. heterotroph), and other characteristics such as reproduction methods and habitat. These traits help scientists determine the evolutionary relationships and distinct characteristics of different organisms to place them within the appropriate kingdom.
Which organisms are eukaryotic?
Plants, animals, fungi, and protists are organisms that are eukaryotic, meaning their cells have a nucleus enclosed within membranes. This nucleus houses their genetic material.
Why is it difficult to classify virus?
Viruses have unique characteristics that differ from other living organisms. They are not made up of cells, do not have a metabolism, and cannot reproduce on their own. This makes it challenging to classify them within traditional biological classification systems designed for living organisms.
What is in each phylum?
Nested within each phylum are subgroups, each more specific than the last. These subgroups include class, order, family, genus and species.
How should scientists classify the organisms between a sea spider and a euglena?
Scientists would classify organisms between a sea spider and a euglena based on their shared characteristics and evolutionary relationships. Sea spiders are classified as arthropods (specifically pycnogonids), while euglenas are classified as protists. These organisms would occupy different phyla within the Tree of Life.
