In this very assignment, we will be learning about the carbon cycle.
First of all how carbon enters the atmosphere?
Carbon enters the atmosphere as carbon dioxide from three sources: respiration, combustion, and decomposition.
The sources of combustion can be combustion of fuel in vehicles, combustion of fuel in industries, forest fires, volcanoes.
So all types of the burning of fuels release carbon into the atmosphere.
Now let's learn the sources of respiration:
All animals respire and release carbon dioxide into the atmosphere.
Now the third source of carbon in the atmosphere is decomposition.
Decomposition of dead remains of all plants and animals releases carbon dioxide into the atmosphere.
So the three sources of carbon dioxide in the atmosphere are respiration, combustion, and decomposition.
Now let's see who consumes this carbon dioxide from the atmosphere.
Carbon dioxide is consumed by producers or plants to make carbohydrates with the process of photosynthesis.
So carbon dioxide is used by producers i.e., all the plants, and carbon dioxide becomes parts of these producers.
Now these producers are consumed by all the consumers
That is all herbivores and omnivores and then carbon dioxide becomes the part of these herbivores and omnivores.
These herbivores and omnivores are consumed by carnivores and thus carbon becomes the part of carnivores also.
So carbon becomes a part of all producers and consumers.
Now, what happens when these producers, as well as consumers, die.
The dead remains of both producers as well as consumers are decomposed by decomposers, that is the carbon in their bodies is returned to the atmosphere as carbon dioxide.
And these dead remains of plants and animals, that are buried for thousands of years turn into fossil fuels, and we use them for combustion that too releases carbon into the atmosphere.
So this is how carbon dioxide or carbon circulates in the atmosphere.
I hope you liked our video.
Kids should spend time watching informative videos and expand their knowledge day by day.
Kids retain what they see in audio-visual lessons so make them watch informative videos rather than cramming things.
If you want to learn any topic, please free to write to us, we will upload the video to help you out as soon as possible.
We can also create a customized u tube playlist for the topics you want to learn.
Your feedback is important to us.

About us:
Welcome to Tutway.
A unique platform where learning is fun.
Now there is no distinction between kids’ fun time and study time.
At Tutway, we believe in a very simple idea that audio-visual learning is the most effective tool for grasping knowledge. Many researchers have proven that kids learn a lot by playing interactive games and watching audio-visual animated lessons as compared to reading from books.
That's when Tutway comes to the rescue.
Tutway is a supplementary education program where kids can learn at their own pace. The students can watch animated videos that are so meticulously made that they can understand even the most complex concepts very easily. There is a question bank at the end of each video where students can answer those questions multiple times and test whether they have grasped knowledge completely or not.
That is why; Tutway has thousands of animated videos on Maths, English, and Science to clear the basics of these subjects. It perfectly suits most of the educational needs of most of the students, regardless of their learning abilities.
So hurry up, download the Tutway app and book a free-demo class to make education interactive and fun experience.
