IELTS ACADEMIC WRITING TASK 1
The diagram below illustrates the carbon cycle in nature. Write a description of this diagram for a university lecturer.
SAMPLE ANSWER
The diagram shows how carbon moves through various stages to form a complete cycle. This report will give a brief description of the main stages in this cycle.
Overall, we can see that carbon moves in a natural cycle, although human factors may now be affecting the balance.
First, we can see that energy from the sun is transformed into organic carbon through a process in plants known as photosynthesis. This organic carbon is then transferred underground when plants, and the animals that feed on them, die and decay. Some of this carbon is trapped underground in the form of fossils and fossil fuels.
Carbon is also released back into the atmosphere, however, through various means. One is when animals and plants respire, and another is when humans burn fossil fuels in cars and factories. All this carbon enters the atmosphere as CO2. It is then reabsorbed by plants, and the cycle begins again.
