The order of the building blocks of life in sequence of largest to smallest should be
cell -> tissue -> organ -> organ system -> organism ->
Biosphere-> Ecosystem-> Community -> Population -> Organism -> Organ System ->Tissue -> Cells
The right answer is chromosome > DNA > gene.
Living cell element, of characteristic shape and in constant number, located in the nucleus of the cell.
DNA, which is our chromosome, carries the genes . The DNA molecule, also known as deoxyribonucleic acid, is found in all our cells.
The gene is a piece of this DNA that corresponds to a particular genetic information that codes for a single protein. So it's a very small portion of chromosome.
