Classification of Animal Kingdom
Kingdom is a widely studied topic on Biology. There are many types of kingdoms. Further there are many classifications of animal kingdom.
Animal Kingdom is a term used in the biological classification of living things. There are many classifications of living things, but the animal kingdom is one of the most common. The animal kingdom is divided into two parts: vertebrates and invertebrates. Vertebrate animals have a backbone while invertebrates don’t.
Classification of Animal Kingdom
One method of classification of animal kingdom is based on the animal’s level of complexity. This method divides animals into two categories: simple, and complex, Simple animals are those that have only a few basic body parts and functions. Complex animals have more body parts and more sophisticated functions.
Another method of classification of animal kingdom is based on the animal’s habitat. This method divides animals into two categories: terrestrial and aquatic. Terrestrial animals live on land, while aquatic animals live in water.
The third method of classification of animal kingdom is based on the animal’s diet. This method divides animals into three categories: carnivores, herbivores, and omnivores. Carnivores are animals that eat only other animals. Herbivores are animals that eat only plants. Omnivores are animals that eat both other animals and plants.
No matter which method of classification of animal kingdom you use, there is a lot of diversity within each category. For example, within the category of terrestrial animals, there are many different types of creatures, such as mammals, reptiles, birds, amphibians, and insects. And within the category of aquatic animals, there are also many different types of creatures, such as fish, crustaceans, mollusks, and jellyfish.
Many Different Animal Kingdoms
There are many classifications of animal kingdom, however the most common one used is by the kingdom.
The six kingdoms are Eubacteria, Archaebacteria, Protista, Fungi, Plantae, and Animalia.
Eubacteria are also known as true bacteria and they are single-celled prokaryotic organisms.
Archaebacteria are a type of bacteria that live in extreme environments such as hot springs or deep-sea vents.
Protista is a single-celled eukaryotic organism that can either be plant-like, animal-like, or fungus-like.
Fungi are eukaryotic organisms that include yeast, mushrooms, and molds.
Plae is eukaryotic and includes all the green plants on Earth.
Animalia is a large group that contains all multicellular animals. Another is the domain.
The three domains are Archaea, Bacteria, and Eukarya.
Domain Archaea contains the archaebacteria while Domain Bacteria contains the eubacteria.
Domain Eukarya is made up of all plants and animals and it is this group that we humans belong to. It may also be helpful to know that there are two types of prokaryotic cells, gram-positive and gram-negative.
Gram-positive bacteria have a thick cell wall covered in a type of protein called peptidoglycan.
Gram-negative bacteria do not have this peptidoglycan layer and their cell walls are thin and delicate.
Bacteria can be further classified by their shape.
There are three shapes: coccus (spherical), bacillus (rod-shaped), and spirillum (spiraled).
Cocci are the simplest form of bacteria while spirilla are the most complex.
Conclusion
Animal kingdom classification is a very vast topic. These are the five different levels of animal classification. Each level has its own unique characteristics that make it different from the others. Knowing these differences can help you understand more about the animal kingdom and how it is organized.
