All matters are made by atoms, molecules, macro, and bulky molecules. Nature, we call some matter living and others non-living. But both living and non living things are interrelated with each other. In this material world, matters can be classified into the following ways.
- Non-living things
- Living things
What are Non living things?
Non living things are not having any life in this world. Starting from small, all the atoms are non living things. Even though, atoms have the period revolution of electrons around their nucleus and possess internal vibration energies, etc.
small Molecules also considered non living things. Even though they have all different forms of energy. When it comes to large size molecules, then the picture changes. Proteins are made by the sequence arrangement of amino acids. DNA and RNA are made by the sequence of nucleobases. These biomolecules undergo constant folding and unfolding (dynamics).
All protein, DNA, and RNA are considered non living things. Now let us see how living things orginated.
How living things originated?
By combining these proteins, DNA, lipids, and RNA are some have self assembled in unique ways to form cells. All living things are made by these living cells. It undergoes reproducibility, growth and moves .
Living Things on the earth
Non-Living Things on the earth
|They made life on the earth.||They do not possess life on the earth.|
|Living things are capable of giving birth to their young ones. This thing is called reproducibility.||Non-living things do not reproduce by themselves. They maintain a constant level.|
|For survival in this world, living things depend on water, air, land, and food.||Non-living things have no such requirements and stay in their own ways.|
|Living things are sensitive and responsive to external and internal stimuli.||Non-living things are not responsive and do not react to internal and external stimuli.|
|Metabolic reactions of cells constantly occur in all living things. This is called the metabolism of living things||No metabolic reactions in Non-living things. They are called non-metabolic in nature.|
|Living cell organisms undergo growth and development in different stages.||Non-living things do not grow or develop very slow process. It may take million or billion years for the growth of mountains.|
|They have a lifespan and are not immortal in this world.||They have no lifespan and are immortal in this world. They stays million or billion years in this planet.|
|Living things move from one place to another externally and internally.||Non-living things cannot move from place to another by themselves.|
|They respire and the exchange of gases such as oxygen and carbon dioxide takes place in their cells. Some rare cases bacteria takes or evolve hydrogen sulphide, ammonia etc,.||Non-living things do not respire any gases.|
|Example: bacteria, amoeba, Humans, animals, plants, insects.||Example: Rock, stone, soil, pen, buildings, paper towels, gadgets.|
