In this Academic IELTS Writing Task 1 post we are discussing another cycle diagram related to the environment or atmosphere. You will find a great model answer to a cycle diagram which shows how carbon moves on and around the atmosphere. You will also get a short vocabulary practice on the model answer.

Let’s take a look at the question.

The diagram shows the movement of carbon on and around the atmosphere.

Model answer:

The illustrated diagram is a clear presentation of how carbon moves on and around the Earth’s atmosphere. Overall, the diagram indicates that carbon movement on the earth is an ongoing process that includes both natural and man-made practices.

As is shown in the diagram, carbon-di-oxide or CO₂ gas is one of the main sources of carbon in our environment and it is created due to two major exercises. The natural exercise includes both plants and animals. Using the sunlight plants produce food through photosynthesis reaction which creates CO₂. Plants also release CO₂ gas and carbon in the atmosphere and below the surface through respiration. Animal respiration also contributes by discharging carbon dioxide into the atmosphere which comes back to the surface with rainfall. Carbon is also discharged on the surface level and absorbed by water owing to the death of organisms and wastes as well as fossils and fossil fuels beneath the ground.

The other one is the man-made exercise which includes factory wastes and emissions and exhaust release which are responsible for a large amount of carbon-di-oxide discharge on the environment.
