Class 7th respiration in organisms

What is Respiration?

Respiration is a biological process where living organisms take in oxygen and give out carbon dioxide. This process helps to produce energy that is essential for growth, movement, and other life functions. It happens in every cell of our bodies and is crucial for our survival.

Cellular Respiration

Cellular respiration is the process that happens inside the cells to produce energy. It's like the power factory of cells. Here, the food we eat is converted into energy that our body uses for all its functions. There are different types of cellular respiration, mainly aerobic and anaerobic respiration.

Aerobic Respiration

Aerobic respiration happens in the presence of oxygen. It is the most efficient way to produce energy and is usually how humans and many animals respire. In aerobic respiration, oxygen helps to break down food materials like glucose to produce a large amount of energy.

Anaerobic Respiration

Anaerobic respiration occurs when there is no oxygen available. This is less efficient than aerobic respiration and happens in some bacteria, yeast, and even in our muscles when we exercise very hard. The energy produced here is less compared to aerobic respiration.


Breathing is the physical act of taking in oxygen and releasing carbon dioxide. It's how our lungs work. When we breathe in, our lungs fill with oxygen, which is then sent to all parts of the body. When we breathe out, we release carbon dioxide, which is a waste product.

Breathing Rate

The breathing rate is how many breaths we take in a minute. This rate can change based on what we're doing. For example, when we exercise, our breathing rate goes up because our body needs more energy. When we sleep, the rate goes down because our energy needs are less.


Breathing isn't just for humans; all animals need to respire too, but the way they do it can be different.


An earthworm breathes through its skin. It doesn't have lungs like humans. Oxygen passes through its moist skin and goes directly into its bloodstream.


A cockroach has tiny tubes called tracheae for breathing. Air enters through small holes in its body and is transported to cells via these tubes.


Fish breathe using gills. They take in water through their mouths, and the gills take the oxygen from the water. The gills then release carbon dioxide back into the water.

In summary, Class 7th Respiration in Organisms covers a lot of ground, from understanding what respiration is to exploring its types like aerobic and anaerobic respiration. It also delves into the practical aspects like breathing and breathing rate, and even extends the learning to how other animals like earthworms, cockroaches, and fish breathe. This topic is not just informative but also fascinating, helping us appreciate the complexity and beauty of life.
