A living creature that has an organized structure, is capable of responding to stimuli and can reproduce, develop, adapt, and preserve homeostasis is referred to as an organism. The fundamental building blocks of both living beings and non-living things are molecules. Every group of organisms is made of these molecules or cells. The total number of species on Earth is 8.7 million, including 6.5 million species on land and 2.2 million in the oceans. There are 6 main types of organisms on the planet. Humans cannot survive without food but surely animals and other creatures can. Let’s dive into the article and discuss what is organism made of and many more interesting topics about the group of organisms.
1. What are called Organisms?
Every animal, plant, fungus, bacterium, and other creature found on Earth would be considered an organism. Organisms can be unicellular or multicellular. Even though they only have one cell, unicellular creatures are very complicated. There is a vast network of compartments and chemicals that execute particular tasks inside cells. These molecules are the building blocks of the compartments inside cells called organelles, and organelles collectively make up cells. (See What are the Three Parts of Cell Theory?)
2. What is Organism made of?
As we all know, the cell is where it all begins. For some organisms, the cell is where it stops. However, cells join to create tissues, which then develop into organs, and organs into organ systems, which then come together to make an organism. They give the body a clear structure, aid in the digestion of food, and release energy that is used up by our bodies as we go about our daily activities. Cells help in smooth and fuss-free living. They contain lipids and molecules that help in carrying out various activities.
The jobs that cells carry out determine their shapes and sizes. An example is, Amoeba constantly alters its shape as it moves by doing so. (See Why is DNA Replication Critical to the Survival of Organisms)
3. Can you give 3 Examples of an Organism?Photo by Michael Schiffer on Unsplash
- An illustration of an organism that lives in society is the bee. To gather sugary nectar from flowers and store it in their hive, they work very hard. They cooperate to construct and maintain the hive while safeguarding it.
- The great white shark is the pinnacle of the marine food chain and the definition of a predator. Due to their great sense of smell, sharks may locate dead bodies and injured animals by following the scent of blood for kilometers under the sea.
- An organism can be as simple as a bacterium, which is a DNA molecule with genetic material encased in a plasma membrane for protection. Organisms frequently keep their information molecules separate from the environment to prevent damage from pH changes and unidentified substances.
4. What are the Types of Organisms?
Though only a small portion of them have been identified, there are an estimated 10 million to 14 million distinct species living on Earth today. Producers, scavengers, parasites, consumers, predators, carnivores, omnivores, herbivores, and decomposers are only a few of the numerous sorts of life.
- The sun is used by producers to create their food. These organisms are virtually always made up of plants and other single-celled creatures.
- Organisms called scavengers hunt down dead animals and consume them. They are essential to our environment because they clean up the waste left behind by other creatures.
- A parasite is an organism that lives on, in, or feeds on another one. An organism that a parasite is feeding on may suffer harm from it or possibly die as a result.
- Animals or plants are consumed by consumer creatures. They can be classified as primary, secondary, or tertiary consumers.
- Predators must rely on plants or other creatures, referred to as their prey, for nourishment.
- Carnivores solely consume, kill, and hunt other animals. Obligate and facultative carnivores are the two different categories.
- Animals and vegetation are consumed by omnivores. They have restrictions on what they can and cannot consume.
- Only plants and other greens are consumed by herbivores.
- Decomposers use the breakdown of dead plants and animals to provide energy.
So, we just saw the group of organisms and now let us see an example of a group of organisms – The Empire Algae and protozoa are only two examples of the wide range of creatures that make up the phylum Protista. Its constituents are eukaryotes, yet they are not fungi, mammals, or plants. Protists can be colonial, multicellular, or unicellular. All protists need mitochondria for aerobic cellular respiration.

5. What are the 6 Main Types of Organisms?Photo by sohail nachiti on Pexels
The 6 main types of organisms are Plants, Animals, Protists, Fungi, Archaebacteria, and Eubacteria. now let us understand a bit about these kingdoms.
- As we all know, plants serve as both a source of food and shade while also producing their energy through photosynthesis. They consist of mosses, ferns, and flowering plants, and they are multicellular.
- With over one million species, animals make up the largest group and are heterotrophs since they must hunt to exist.
- Archaebacteria are unicellular microorganisms that can only survive in harsh environments.
- Fungi have complex cells and feed on plants that have decomposed in the soil. They have an appearance similar to plants, such as mold, mildew, and mushrooms.
- Protists typically have one cell. They can move around in their environment and have moving parts as well. You might be wondering why those protists aren’t included in the kingdoms of Eubacteria or Archaebacteria. Protists are sophisticated cells, in contrast to bacteria.
- Eubacteria are generally useful and found everywhere. Vitamins and foods like yogurt are produced by some eubacteria and they are single-celled complex organisms.
6. How are Organisms Classified?
After learning about the 6 main types of organisms now it is time to understand the divisions and sub-divisions of organisms.
The kingdom is the highest rank. It is split up into groups called phyla, or divisions, which are then further broken down into classes. Classes are then followed by order, family, and genus, and end with species as the lowest taxonomy rank. Thus, the fundamental unit of classification is the species.
These divisions have made it easier for scientists to conduct their research and for students to comprehend how and under what conditions the Earth’s living organisms arose. When you are aware of a structure’s inner workings and existence, you can solve any problem or comprehend it. Check out What is the Most Specific or Smallest Level of Classification?
7. What do you call a Group of Organisms?
A group of organisms is called Taxon. Adolf Meyer first used the term taxon to describe an animal in 1926, then it was first used in 1948. It indicates the taxonomic rank of any group.
This taxonomical division or classification is done based on the biological characteristics of the creatures and to know their individuality and survival modes due to the existence of complicated and many organisms nearby. (See When is Cladistics more useful than Linnaean Taxonomy?)
8. What is an Example of a Group of Organisms?
An example of a group of organisms is specie. A group of creatures that can breed with one another in nature and create healthy offspring is referred to as a biological species.
Another way to categorize a group of organisms is according to their shared ancestry and evolutionary history. (See Oldest living species alive today)
9. What are the 7 Groups of Organisms?
Living things can be categorized according to traits including appearance, reproduction, mobility, and functionality, to name just a few. The taxonomy of living things refers to the specific division or group of organisms.
- Depending on how they receive their nourishment, the types of cells that make up their bodies, and the number of cells they contain, living beings are classified into different kingdoms. There are 5 kingdoms namely- Monera, Protists, Fungi, Plant, and Animal.
- The phylum comes after the kingdom. It is an effort to identify any physical similarities between creatures belonging to the same kingdom.
- A phylum’s creatures can be further broken down into classes. As you would have guessed, species within a class share even more characteristics than those across the entire phylum.
- Orders are used to further categorize the organisms in each class. To discover which order an organism belongs in, utilize a taxonomy key that shows that more similarities exist between members of a family than at any other classification level. Organisms belonging to the same family are referred to as being related because they have so much in common.
- Genus is a term used to describe an organism’s generic name. Since each genus is classified very precisely, there are fewer organisms in each.
- The classification of living things at this level is the strictest and lowest possible. The ability to reproduce with other members of the same species is the primary criterion for an organism to be classified as belonging to a specific species.
10. Is Human an Organism?
The Hominidae Family contains humans. Therefore, since they depend on food and water for survival and have cells in their intricate structure to enable them to stay alive and perform everyday tasks, people are undoubtedly a major part of a group of organisms.
The most advanced species that can decide, reflect, and respond is the human. None of the other species in the world have as many amenities built into them as humans have. The fact that humans were once an adolescent, and before that, a kid, an infant, a fetus, and an embryo states that we are living organisms. Hence, in many ways, a complete, living member of the Homo sapiens species even as an embryo is still developing. (See What are Examples of Living Things)
