- Anatomical traits alone cannot classify microscopic unicellular creatures into functional groupings.
- Organisms without evident traits are excluded from classification based on biological properties.
- Pure culture cannot support the growth of many species, which restricts analysis.
<h3>Microorganism :</h3>
Microorganisms, often known as microbes, are minute organisms that can be either single cells or colonies of cells. Ancient texts, including those found in India's Jain scriptures from the sixth century BC, express suspicions about the potential existence of unseen microscopic life. bacteria, archaea, fungus (yeasts and molds), algae, protozoa, and viruses are the main categories of microorganisms.

Why microorganisms are important ?</h3>
In addition to producing oxygen and carbon dioxide, microorganisms also fix atmospheric nitrogen into forms that are useful to a variety of creatures. They contribute to the gut microbiome, which aids in the digestion of food by animals. Some microbe species are symbiotic by nature.

Over millions of years, dead plants and animals started to form into organic material than were turned into fossil fuel,
Fossil fuel is basically made from fossils from organic matter coal is made from dead trees.
Line graphs can also be used to compare changes over the same period of time for more than one group. Bar graphs are used to compare things between different groups or to track changes over time.
Inter-neurons, also known as associative neurons, are housed entirely within the central nervous system. They have short dendrites and may have either a short or long axon.
Each neuron has three parts such as cell body, dendrites and a single axon. Inter-neurons are connected spinal motor and sensory neurons. Transferring signals between sensory and motor neurons, they also communicate with each other .
These inter-neurons are 20 billion in numbers and mostly found in the brain and spinal cord and within automatic ganglia. They make >99% of all neurons in the body. Relays signals between a sensory neurons and motor neurons.
