The taxonomic hierarchy is a system for classifying living organisms from the most general to the most specific categories, or taxa, using a hierarchical ranking. The standard eight ranks, from broadest to most specific, are Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species. This classification, based on the Linnean system, helps scientists understand relationships between organisms and communicate effectively about them.

What is Taxonomy? -Greek word “taxis” meaning arrangement or division and “nomos” meaning method -Taxonomy is a branch of Biology that refers to the process of classifying different living species.
Taxonomic hierarchy is the process of arranging various organisms into successive levels of the biological classification either in a decreasing or an increasing order from kingdom to species and vice versa.
Taxonomic hierarchy is the process of arranging various organisms into successive levels of the biological classification either in a decreasing or an increasing order from kingdom to species and vice versa. Domain classification is the highest level of biological classification that groups organisms into domains. The three domains of life are Archaea, Bacteria, and Eukarya.
Taxonomic hierarchy is the process of arranging various organisms into successive levels of the biological classification either in a decreasing or an increasing order from kingdom to species and vice versa. The kingdom is next to domain level of classification, which is divided into subgroups at various levels.
Are prokaryotic, unicellular organisms. They reproduce through binary fission Ex. staphylococcus, bacillus, spirilla KINGDOM MONERA
Protists are unicellular in nature but can also be found as a colony of cells. Most protists live in water, damp terrestrial environments or even as parasites. KINGDOM PROTISTA
Were once considered plants but scientists discovered that they cannot produce their own food; non-photosynthetic; multicellular and eukaryotic organism KINGDOM FUNGI
It includes all the plants. They are eukaryotic, multicellular and autotrophic organisms. The plant cell contains a rigid cell wall . Plants have chloroplast and chlorophyll pigment, which is required for photosynthesis. KINGDOM PLANTAE
It constitutes all animals. Amongst the five kingdoms, the largest kingdom is the animal kingdom. Animals are multicellular eukaryotes. However, like plants, they do not possess chlorophyll or a cell wall. Therefore, members of the animal kingdom exhibit a heterotrophic mode of nutrition. KINGDOM ANIMALIA

The Role of Classification Classification of living things allows us to: Organise and categorise species based on shared characteristics. Provide a universal system for communication and information exchange. Reveal evolutionary relationships and common ancestry. Help with scientific research, conservation efforts and studies of biodiversity.
Benefits of Classification Here are some of the advantages of grouping organisms: Enhances our understanding of biodiversity Enables people from around the world to communicate effectively about living things Allows us to identify new species in remote habitats Allows us to name organisms that we are unsure about Assists us in ecological studies and species conservation
Drawbacks of Classification Grouping organisms also has its disadvantages. Here are a few of them: Sometimes challenging due to complex scenarios or evolving organisms Physically similar organisms may not be related genetically Some organisms may have characteristics that don’t fit neatly into existing categories Can be very subjective and inconsistent
Its body and head are similar to a mouse. It has barely visible front legs, similar to prairie dogs. It has powerful legs and jumps can be compared to a kangaroo. Mystery Creature Can you guess this mystery creature given the following characteristics?
It’s a gerbil! A gerbil is neither a mouse, squirrel, rabbit, tiny kangaroo, cat, lemur or prairie dog. Although it exhibits typical characteristics of each of them, a gerbil is a unique member of the family of ‘dipodids’ or jumping rodents! Mystery Creature
A RECAP Classification Why classify? How to do it? It is the process of grouping organisms based on shared characteristics. We can better understand the diversity of life on Earth today when we group organisms. We can identify several species with careful observation and the help of tools like dichotomous keys.
