Important Topics in NCERT Exemplar Solutions for Class 7 Science Chapter 2 – Nutrition in Animals

Human Digestion 

In CBSE Class 7 Science NCERT Exemplar Chapter 2, you will learn about human digestion in a very detailed manner. The chapter included explanation through theory, examples and a well-detailed diagram where all the organs involved in digestion have been shown. 

In this chapter, you will get to know that the food after being consumed, passes through the food canal. This food canal is divided into various compartments which are – the buccal cavity, the food pipe known as the oesophagus, the stomach, small intestine, the large intestine which ends in the rectum and the last part is the anus. 

The digestive tract comprising these parts and the glands which are associated with it is together known as the digestive system. Each part has been explained in detail in the exemplar problems of this chapter along with their individual analysis and diagrammatic representation. 

Digestion in Grass-Eating Animals 

Grass-eating animals like cows and buffaloes have a different mechanism of digestion. They eat at a very fast pace without chewing and tend to store the food in their rumen which is a part of their stomach. The food stored there gets digested in a partial manner and later returns to the mouth of the animal in the form of smaller lumps. 

Digestion in Amoeba

Amoeba is a microscopic single-celled organism which has a cell membrane, a rounded dense nucleus and many small vacuoles. Amoeba gets its nutrition from microscopic organisms. The food gets trapped in its food vacuole and the digestive juices are secreted into this vacuole itself.
