Which of the following statements about the human digestive system is true?
Which of the following statements are true/false? i
Nutrients are needed for the survival of all living organisms. Plants get their nutrients from their roots and the energy molecules they need for cellular function by photosynthesis, while animals get their nutrients through eating other organisms. Amino acids, lipid molecules, nucleotides, and simple sugars are the biological molecules needed for animal function at the cellular level. The food eaten, on the other hand, is high in protein, fat, and complex carbohydrates. These macromolecules must be converted into the simple molecules needed for cellular function by animals. Digestion and absorption are both involved in the conversion of the food eaten to the nutrients needed. Food particles are broken down into smaller components during digestion, which are then consumed by the body. This occurs by both physical and chemical processes, such as chewing.
Maintaining a balance between food intake, storage, and energy expenditure is one of the most difficult aspects of human nutrition. When more food energy is consumed than is expended in operation, the surplus is stored as fat deposits. The increase in obesity and the diseases that result from it, such as type 2 diabetes, emphasizes the importance of recognizing the role of diet and nutrition in preserving good health.

Which one of the following statements is not true
Animals get their nutrition by eating other species. Animals may be divided into three groups based on their diet: herbivores (plant eaters), carnivores (meat eaters), and omnivores (those that eat both plants and animals) (omnivores). Food contains nutrients and macromolecules that are not readily available to the cells. Within the animal body, a variety of processes change food in order to make nutrients and organic molecules available for cellular function. Animals’ digestive systems have evolved to meet their diverse nutritional needs as their shape and function have become more complex.
Herbivores are animals that eat plants as their primary source of nutrition. Herbivores include vertebrates like deer, koalas, and some bird species, as well as invertebrates like crickets and caterpillars, as shown in Figure 15.2. These animals’ digestive systems also evolved to handle vast quantities of plant matter. Frugivores (fruit eaters), granivores (seed eaters), nectivores (nectar feeders), and folivores are the different types of herbivores (leaf eaters).

8) Which of the following diets would be best for providing the energy needed for ATP and biosynthesis by animals’ digestive systems? D) a diet that corresponds to the species’ food pyramid.
13) Fats are broken down during digestion as fatty acids are separated from glycerol. Proteins are also digested to produce amino acids. What are the similarities and differences between these two processes?
