Question

Which of the following is a non-living thing?

Answer 1

Hint: the accumulation of non-living materials on the surface. So, it is not considered as real growth.The thing which is incapable of growth, movement, metabolism, and reproduction is known as a non-living thing. These things do not possess any life in them. A few examples of non-living things are rocks, bed, newspaper, clothes, bedsheets, and naturally occurring events like rockfalls, floods, or earthquakes.

Complete answer: Living organisms have certain characteristics which include:
-Growth is a defining characteristic of all. Living organisms grow. Growth can be an increase in mass and an increase in the number of individuals.
-Reproduction is also an important characteristic of a living organism. Multicellular organisms produce progeny approximately similar to themselves. Organisms also reproduce asexually.
-Metabolism is also one of the characteristics of all living organisms. Living organisms are comprised of chemicals. Metabolic reactions continuously occur in a living body.
-The cellular organization is a defining feature of living beings. All living organisms are made of cells or are just a single cell.
-Consciousness is the defining property of all living organisms. Living organisms have the ability to sense their surroundings and respond to external stimuli. This stimulus can be physical, chemical, or biological. All the three options B, C, and D possess all the above characteristics and hence are living organisms except the table.
So the correct answer is option A.

Note: Growth is an important characteristic of living organisms. The increase in body mass is one of the conditions of growth. Some non-living objects also grow if the increase in body mass is considered as growth. By this means, mountains, boulders, and sand mounds grow with time. But the growth which is exhibited by the non-living objects is only by
