Chapter 01 – Classification of Living Things
The classification of living things involves organizing life forms based on shared characteristics. The word taxonomy is the term used to describe the classification of living things. The basic taxonomy of living things includes six kingdoms.

Chapter 05 – Matter and Changes in its States
State changes are physical changes in matter. They are reversible changes that do not involve changes in matter's chemical makeup or chemical properties. Common changes in the state include melting, freezing, sublimation, deposition, condensation, and vaporization.

Microorganisms

“Microorganisms are minute organisms that are invisible to the naked eye.”

Microorganisms are so small that they can only be seen under a microscope. These include a huge range of organisms such as bacteria, viruses, fungi, algae, protozoa, etc. These microbes can be beneficial as well as harmful in many ways.

The air we breathe, the food we eat, the water we drink, the floor where we stand, everything around us is inhabited by some or the other type of microorganism. They are even present inside our body.

Virus, bacteria, and fungi.

In all cases, bacteria, fungi, and viruses infect one cell or one tissue and then start to spread around the body infecting multiple other cells or tissues, in some cases killing humans. One common symptom of most bacterial, fungal, and virus infections is fever.
