Amino acid autotrophs and amino acid heterotrophs Amino acid autotrophs(氨基酸自养型生物) is a group of organism who don't need amino acid as their nitrogen source and can self-synthesize all the amino acids they need using simple nitrogen source as material D dnit Otherwise, amino acid heterotrophs(氨基酸异养型生物) intake ready amino acids as their nitrogen resources. all the animals and a number of heterotrophs are amino acids heterotrophs.Amino acid autotrophs(氨基酸自养型生物) is a group of organism who don’t need amino acid as their nitrogen source and can self-synthesize all the amino acids they need using simple nitrogen source as material.
