FAQs on L3 : Holozoic Animals - Nutrition in Animals, Science, Class 7 Video Lecture

1. What is holozoic nutrition?

Ans. Holozoic nutrition is a type of nutrition in animals where they obtain their food by ingesting and digesting solid organic substances. This process involves the ingestion of food, followed by the breakdown of complex molecules into simpler ones through digestion, absorption of nutrients, and elimination of waste.

2. How do holozoic animals obtain their food?

Ans. Holozoic animals obtain their food by actively searching for and capturing their prey. They have specialized feeding structures such as jaws, beaks, or teeth to catch and consume their food. Some animals, like herbivores, feed on plants, while others, like carnivores, feed on other animals.

3. What is the role of digestion in holozoic nutrition?

Ans. Digestion plays a crucial role in holozoic nutrition as it helps in breaking down complex food substances into simpler ones that can be absorbed by the body. It involves mechanical and chemical processes where enzymes break down proteins, carbohydrates, and fats into smaller molecules that can be easily absorbed by the body.

4. How do holozoic animals digest their food?

Ans. Holozoic animals have a specialized digestive system that helps in the digestion of food. This system includes organs such as the mouth, esophagus, stomach, and intestines. Mechanical digestion occurs through chewing and grinding of food, while chemical digestion takes place with the help of enzymes secreted by various digestive organs.

5. What happens to the undigested waste in holozoic animals?

Ans. Undigested waste in holozoic animals is eliminated from their body through the process of egestion. The undigested food, along with other waste materials, passes through the intestine and is expelled from the body through the anus. This process helps in removing waste and toxins from the body, maintaining proper digestion and overall health.
