Respiration in organisms is an important process for all living things, and understanding it is critical for Class 7 students. Here you'll find all the notes, MCQs and extra questions on respiration you need to ace your exams

Understand the concept of respiration.
Respiration is the release of energy from food molecules and oxygen to produce carbon dioxide, water, and other byproducts such as ammonia. All living organisms — including humans, animals, plants, fungi, and bacteria — undergo respiration as part of their metabolic processes.

The NCERT Class 7 Science textbook covers the topic of respiration in organisms in Chapter 10. Here is a brief summary of the chapter:

The chapter begins by introducing the concept of respiration and its importance in living organisms. It explains the process of respiration and the difference between aerobic and anaerobic respiration.

Next, the chapter talks about the respiratory system in humans and the various organs involved in the process of respiration, such as the lungs, nose, and trachea. It also explains how the exchange of gases, such as oxygen and carbon dioxide, occurs in the body.

The chapter then goes on to discuss the respiratory system in plants and how it differs from that of animals. It explains the process of photosynthesis and how it is linked to respiration.

The chapter also talks about the energy released during respiration and how it is utilized by the body. It explains the concept of ATP and how it is produced during the process of respiration.

Finally, the chapter discusses the importance of breathing exercises and the role of aerobic exercise in maintaining a healthy respiratory system.

In conclusion, the chapter provides a comprehensive understanding of the process of respiration in organisms, the importance of oxygen and carbon dioxide exchange, and the role of the respiratory system in maintaining life. It also emphasizes the importance of maintaining a healthy respiratory system through proper breathing and exercise.
