Concept explainers

Modes of Nutrition

It is a biological process of providing or obtaining food that is necessary for growth and health. It includes many physiological processes - absorption, ingestion, assimilation, catabolism, excretion, etc. In biology, the science that deals with nutrition's physiological and chemical processes are called "nutritional science."

Question

What defines autotrophs (and distinguishes them from heterotrophs)?

Use organic molecules in energy metabolism

Use carbon dioxide in energy metabolism

Use organic molecules in food to biosynthesize organic molecules

Use carbon dioxide to biosynthesize organic molecules

Chemical pathways by which living things function, especially those that provide cellular energy, such as the transformation of energy from food into the energy of ATP. Metabolism also focuses on chemical pathways involving the synthesis of new biomolecules and the elimination of waste.
