Living organisms need nutrients to help break down food to give the organism energy.

gene,chromosome,dna,nucleus, and cell

if you look it up you will get the following stated below

"nitrogenous base, nucleotide, codon, gene, chromosome, nucleus, and cell"\

an easy way to remember it will to be

the gene tells you what it would be you get one from mom and one from dad

you need genes to link and make chromosomes

chromosomes to link into strands of dna

there is dna in the nucleus and the nucleus in inside the cell.

hopefully this helps.
