Hint: The food is the main source of energy production in the animal and since they are heterotrophs they are dependent on the primary producers or consumers for their nutrition. A balanced diet is a diet that contains the proper proportion of vitamins, minerals, protein,
carbohydrates, fats, and fibers.
Complete step by step answer: -Different animals have different modes of food intake based on the body size, structure, and their habitat regulated by evolution. Fishes use particles suspended in the water by a filter-feeding mechanism, earthworms use deposit-feeding as they intake the suspended particles in the soil, honey bees, mosquitoes, etc. use a fluid feeding mechanism for their intake of fluid from other organisms as food, animals like python and others use a bulk feeding mechanism as they engulf the whole organism as their food, and aquatic predators use ram and suction feeding mechanism. Amoeba uses pseudopodia for the ingestion of food whereas humans use their mouths for the engulfment of their food. So based on the mode of the food different animals have different nutrition intake.
-Cooking of food includes heating of food by grilling, steaming, baking, frying that is basically done on the stoves or other cooking instruments outside the body of the animal so is not mainly included in the animal nutrition.
-Nutrient requirement is mainly the amount of carbohydrates, proteins, dietary fats, fibers, minerals, and vitamins required by the body to produce energy for the metabolic processes and the growth of the cell. A balanced diet can reach this nutrient requirement, so this is included in animal nutrition.
-Food once ingested inside the body of the animal is digested where it is broken down into small molecules that can be absorbed. The food is assimilated into the cells of the body and utilized to produce energy to do bodily functions. So, it is included in animal nutrition.
Hence, the correct answer is option (B).
Note: Based on food habits, animals can be divided into herbivores, carnivores, and omnivores. Herbivores only depend only on plants and fruits, carnivores depend on other organisms and omnivores depend on both for their food.
