i) The mouth and buccal cavity :-  
  Food is taken into the body through the mouth. This process is 
called ingestion. In the mouth the food is broken down into smaller 
pieces by the teeth. The mouth has salivary glands which secrete 
saliva. The saliva breaks down starch into sugars. The tongue helps 
to mix the food with saliva and swallow the food.

FAQs on Nutrition in Animals Class 6 PPT

1. What is the importance of nutrition in animals?
Ans. Nutrition is the process by which animals obtain and utilize nutrients for growth, maintenance, and energy. It is essential for the proper functioning of the body, reproduction, and survival of animals. Proper nutrition helps in maintaining good health, strong immunity, and disease resistance in animals.
2. What are the different types of nutrients required by animals?
Ans. Animals require six major types of nutrients: carbohydrates, proteins, fats, vitamins, minerals, and water. These nutrients are essential for the proper functioning of the body, growth, and development, and energy production. A balanced diet with all these nutrients is necessary for animals to maintain good health and avoid nutritional deficiencies.
3. How do animals obtain their nutrients?
Ans. Animals obtain their nutrients from the food they eat. The food is broken down into simpler substances by the process of digestion, and the nutrients are absorbed into the bloodstream and transported to different parts of the body. The nutrients are then utilized by the body for various functions, such as energy production, growth, and repair.
4. What are the common nutritional disorders in animals?
Ans. Some common nutritional disorders in animals are malnutrition, obesity, vitamin deficiencies, mineral deficiencies, and digestive disorders. Malnutrition can occur due to an imbalanced diet or inadequate nutrient intake, leading to stunted growth, poor immunity, and disease susceptibility. Obesity can occur due to overfeeding or lack of exercise and can lead to various health problems. Vitamin and mineral deficiencies can cause a range of health problems, including anemia, bone disorders, and reproductive problems. Digestive disorders such as diarrhea or constipation can occur due to an imbalance in the diet or poor digestion.
5. How can we ensure proper nutrition in animals?
Ans. Proper nutrition in animals can be ensured by providing a balanced diet that contains all the essential nutrients in the right proportions. The diet should be appropriate for the animal's age, breed, and activity level. Regular health check-ups can help detect any nutritional deficiencies or disorders at an early stage. Providing clean and fresh water at all times is also essential for maintaining good health. Regular exercise and proper hygiene are also important for keeping animals healthy and disease-free.
