Question

Which of the non-living things were once a part of the living things?
Butter, Leather, Soil, Wood, Electric bulb, Cooking oil, Salt, Apple, Rubber.

Answer 1

Hint: Living thing refers to the thing that is presently or previously was alive. A non-living thing indicates that thing which is never alive. To categorize something as living, it must have to develop and grow, use energy for their metabolic process, double, must be made up of cells, must show response to the atmosphere, and must adapt itself according to that atmosphere.

Complete answer:
> Butter is a non-living thing but it is obtained from the living thing because it is made up of milk which is obtained from animals.
> Leather is a non-living thing but is obtained from living things. It is used for making purses, shoes, belts, etc. Leather is collected from the skin of the animal.
> Wool is non-living but is obtained from the hair of the sheep which is a living being. It is used in making a sweater as it provides warmth.
> Cooking oil is a non-living thing but it is obtained from the living source i.e. from the seeds of plants.
> Apple is non-living things but it is obtained from a living source that is an apple tree.
> Rubber is a non-living thing but it is initially a part of living beings. Because it is obtained from the latex of the rubber tree.

Hence butter, leather, wool, cooking oil, Apple, rubber all of these are things obtained from the living source. While soil, electric bulb, and salt are the non-living things obtained from the non-living source.

Note: Living things show locomotion because they move from one place to another while non-living things do not. Non-living things are established or demolished by the external force. Living things die over a period while non-living things never die because they do not have cells. Non-living things don’t have a life span. They are lifeless.
