Life is considered a characteristic of organisms that exhibit all or most of the following.
• Homeostasis which is the regulation of the internal environment to maintain a state.
• Organization which is the composition of one or more cell.
• Metabolism which is the ability of transformation of energy by converting chemicals and energy into cellular components.
• Growth which is the increase in size in all of its parts, rather than simply accumulating matter
• Adaptation which is the ability to change over time in response to the environment.
• Response to stimuli which is the response of any living organism. For example the leaves of a plant turning towards the sun.
• Reproduction which is the ability to produce new individual organism.
So taking this into consideration the two items I can put as an example would be a stone versus a plant.
One of the reason for which a stone will be consider a non-living organism and will be different than a plant is because one of the most important characteristic of nonliving things which is protoplasm is absented, as well as cells. Due to the absence of protoplasm, no metabolic activities are possible in the nonliving things. The structural organization like tissue, organ or system is never found in nonliving things, whereas a plant will have cells which will make them a living organism and will have the fundamental basis of life. Although Living and nonliving organism share differences they do have certain similarities they essentially inert and obey physical forces. Thus they both play a very important role in our universe.
