FAQs on Classification of Animals(2) - Animal Kingdom Video Lecture - Class 11
1. What is the classification system used to categorize animals? |
|
Ans. The classification system used to categorize animals is called the Linnaean system or the binomial nomenclature. It was developed by Carl Linnaeus and is based on a hierarchical structure, with animals being grouped into increasingly specific categories such as kingdom, phylum, class, order, family, genus, and species.
2. How are animals classified in the animal kingdom? |
|
Ans. Animals are classified in the animal kingdom based on their characteristics, including their body structure, mode of reproduction, and evolutionary relationships. They are divided into several major groups called phyla, which are further subdivided into classes, orders, families, genera, and species.
3. What are the main phyla in the animal kingdom? |
|
Ans. The main phyla in the animal kingdom include Porifera (sponges), Cnidaria (jellyfish, corals), Platyhelminthes (flatworms), Annelida (segmented worms), Mollusca (snails, clams, octopuses), Arthropoda (insects, spiders, crustaceans), Echinodermata (starfish, sea urchins), and Chordata (fishes, reptiles, birds, mammals).
4. How do scientists classify animals within a phylum? |
|
Ans. Scientists classify animals within a phylum based on shared characteristics. These characteristics may include body structure, presence or absence of a backbone, type of symmetry, mode of reproduction, and other features. By analyzing these traits, scientists can determine which animals belong to the same phylum and further classify them into classes, orders, and other categories.
5. Why is the classification of animals important? |
|
Ans. The classification of animals is important because it helps in understanding the diversity of life on Earth. It allows scientists to organize and study different species, identify evolutionary relationships, and make predictions about the characteristics of organisms based on their classification. Additionally, it provides a framework for communication and research, enabling scientists to share information and build upon each other's work.
