Taxonomical Hierarchy

Question 1: Explain the need for diversity in the environment.

Answer:

Change is a rule of the environment. For the balance of the ecosystem, evolution is important and evolution brings changes in the existing organisms which brings diversity. Diversity leads to creativity and it increases the curiosity of new organisms. For the research and development of organisms, diversity is very much needed.

Question 2: Give the advantages of classification.

Answer:

• Identification of organisms can be determined by classification.
• It gives new scope for the research of organisms and evolution.
• It also tells us the importance of evolution.
• The study of organisms becomes easy and now due to classification, it is easier to learn and memorize living organisms.

Question 3: What is the way to describe the hierarchy of classification.

Answer:

There is a proper sequence of classification from top to bottom in order of increasing the similarities in the organisms which is the Kingdom at the top continued by phylum, class, order, family, genus, and species. Any organism has a proper classification based on this flow. Through this, we can easily know that the organism belongs to which class or order or family.

Question 4: Give the key features of this classification.

Answer:

There are some features on the basis of which the classification is done which are mode of reproduction, presence of membrane-bound organelle, unicellular or multicellular organism, prokaryotic or eukaryotic, mode of nutrition, etc.

Question 5: Give the reason why system of classification changes with time.

Answer:

Due to evolution, there is a change in organisms. Moreover, day by day new organisms is getting discovered. To classify these new organisms, we have to adapt a new system of classification so that the new species can be adjusted in the classification system.

An organism with a different sizes, shapes, modes of nutrition, reproduction mode, habitat, etc. exists on the planet earth. In every species, there are hundreds of similar species which are found to show similar characteristics. Diversity among the living species increases day by day as every day new species are getting discovered so to make their study easy it is very important to categorize these species in an order in which we can remember them that’s why the hierarchy groups are formed to make a better understanding of the species. All the animals may vary in many things like shape, size, nutrition, reproduction, habitat, etc. but they all carry one thing in common i.e., cells. As we all know that all the functions and metabolic activities in our body are performed by cells and these are the building blocks of the body. Tissue is formed from a group of cells that perform similar functions as a group together. The level of organization varies in every organism. The more advance the animal is more advanced its level of organization will be. Diversity can be seen on the basis of many different things like temperature, land, water, etc. Some species can look alike but the genetic makeup of every species is different even if they belong to the same group. This genetic material makes every species unique in its own way. In the evolution over million years, a wide variety of diversity has developed in living species. Human beings have now become homo sapiens from ape-like creatures. To divide species into categories similarities in species are considered.
