All statements are correct. Only IV is wrong. After performing elemental analysis of a plant tissue, animal tissue, microbial paste (living matter) and of a piece of earth’s crust (animate object), it was found that all living and non-living systems are made-up of same chemicals i.e., elements (e.g., carbon, hydrogen, oxygen and several others)
Most living organisms have relatively high abundance of carbon and hydrogen than in earth’s crust
