The flow of energy moves through living organisms via the food chain. A food chain is a diagram which shows how every living thing gets energy to live. Plants use the sun, nutrients in the soil and water to generate energy. Herbivores eat the plants to generate energy to survive. Carnivores eat the herbivores to generate energy.

Answer:
The correct answer is option - b. chemical structure of DNA.
Explanation:
Studying the chemical structure of the DNA molecule is comes within the molecular genetics. Molecular genetics is the subdiscipline of genetics that includes the study of function and structure at the molecular level of the genes with the help of methods of genetics and molecular biology.
The molecular genetics can help in the study of mutation, heredity, and variation with the knowledge of chromosomes and genes.
Thus, the correct answer is option B. chemical structure of DNA.
