It is a wonderful photo of an elephant family. Isn’t it? The big elephant with larger tusks than the smaller elephant is the father, and the middle-sized elephant is his mother elephant. The little elephant next to her is their child elephant. It is a happy family!
I must assume you also agree to the following details about this picture. Because I don’t know the names of these living organisms, I used the words big, large, medium and little to introduce them.
I was able, using some criteria to classify these elephants.
Definition of living Organisms: This is the way that living organisms are grouped into sets or groups. I also did a class in some type of.
Here is a picture with another cute puppy. Did they charm you? Yeah! I hope so. One puppy got dark brown and white colored fur, while another puppy showed a light brown color with some white spots.
Perhaps you realize that I used another method to classify the 2 living organisms. This was based on their fur colors.
After a long year of boring work, you might meet these cute puppies and this elephant family. Would you think that this little elephant would be the same? Do you think you could mention him with “The Little One?” Or would the light brown puppy display the exact same coloring?
All these questions turned out to be a Big NO! Since the size and color of a live organism are based upon their growth, whereas the health status, melanin amounts, and other factors determine the color. If you use growth, color or another criterion for classification, it will be different after some time.
Because such criterion is an artificial criterion. It is because of this reason that we need a natural classification criterion. This allows us to classify all living beings.
Natural Classification of Living Organisms – Features
- Natural classification is the process of determining the relationship between living organisms.
- All characteristics would be considered to create an effective classification that lasts.
- Similar groups of living organisms share a common bond about similar natures.
- The evolution of living creatures can be seen through natural classification.
- The classification factors used for this type of classification are stable and will never change.
Do you know that modern natural classification of living creatures is based on a modified version from the original system developed by Carolus Lindaeus in 1740s.
Main groups of living organisms
Living organisms are built with cells. The cell walls of one group have the cell membrane, while the cells of the other get the cell walls. All living organisms can perform the following tasks:
- Reproduction
- Responding to external stimuli
- Growth
- Regular metabolism
You could easily classify all of the living organisms in the Earth as animals and plants using the above factors. However, it would be unfair to divide all the organisms into two groups when looking at their external features. All organisms must have direct relationships within their group. It’s just not fair.
Take a moment to think about how you would group a non-cellular bacteria with an animal or a amoeba (unicellular) with a human. This is why there are three main types of organisms, according to the natural classification for living organisms. They are animals , flowers , microorganisms.
