FAQs on Nutrition in Animals Class 6 Worksheet Science Chapter 2
| 1. What are the different types of nutrition found in animals? |  |
Ans. Animals exhibit two main types of nutrition: autotrophic and heterotrophic. Autotrophic animals, like some protozoa, can produce their own food using sunlight or chemical processes. However, most animals are heterotrophic, meaning they obtain their food from other organisms. Heterotrophic nutrition can be further classified into herbivorous (plant-eating), carnivorous (meat-eating), and omnivorous (eating both plants and animals).
| 2. How do herbivorous animals digest their food? | |
Ans. Herbivorous animals have specialized digestive systems to break down plant materials. They possess a longer digestive tract to allow for the fermentation of cellulose, which is a primary component of plant cell walls. Many herbivores, such as cows and sheep, have a multi-chambered stomach, which helps in the breakdown of tough plant fibers through microbial fermentation.
| 3. What is the role of enzymes in animal nutrition? | |
Ans. Enzymes play a crucial role in the digestion of food in animals. They are biological catalysts that speed up the chemical reactions required to break down complex food molecules into simpler forms. For example, amylase helps in the digestion of carbohydrates, proteases break down proteins, and lipases assist in the digestion of fats. This enzymatic action is vital for the absorption of nutrients.
| 4. Why do carnivorous animals have sharper teeth compared to herbivores? | |
Ans. Carnivorous animals have sharper teeth, known as carnassials, which are adapted for tearing and cutting flesh. These teeth help them efficiently catch and consume their prey. In contrast, herbivores have flat, molar-like teeth designed for grinding plant material. The differences in tooth structure reflect the dietary needs and feeding habits of each type of animal.
| 5. How do animals absorb nutrients after digestion? | |
Ans. After digestion, nutrients are absorbed primarily in the small intestine. The inner lining of the small intestine is covered with tiny finger-like projections called villi, which increase the surface area for absorption. Nutrients such as amino acids, simple sugars, fatty acids, vitamins, and minerals pass through the intestinal walls into the bloodstream, where they are transported to various cells and tissues in the body for use.
