IELTS Academic Task 1 Correction: Carbon Cycle.

The diagram below shows the carbon cycle.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

20 minutes, 150 words at least.


The diagram provides information regarding the carbon cycle. 

Overall, it can be seen that different processes, which include both man-made and natural, facilitate the cycle. 

The cycle begins when plants undergo photosynthesis, whereby plants they absorb sunlight and (do not use your own knowledge in task 1. Stick to the information in the question) carbon dioxide that is in from the atmosphere. Subsequently, plants they are also ingested by animals and some of the carbon dioxides go dioxide goes back into the atmosphere as animals undergo respiration. (This sentence can also be written in ACTIVE VOICE: Subsequently, animals consume them and return carbon dioxide to the atmosphere through the process of respiration.)

The next process which is called sedimentation (please read carefully – its decomposition) begins, as animals and plants die. This is quite essential for the formation of fossils or fossilization. (1) Then, oil, gas, and coal are extracted into by factories for human consumption. For example, they are used to fuel cars where when they undergo combustion. However, (This cohesive device is unnecessary as there is no contrast here. Note point 1. Please do not allow your knowledge to interfere in task 1. These are just facts – one leading to another. No contrast here.) these create pollution and some (we don’t know the extent.) carbon dioxide are is released into the atmosphere again. 

1. Note that sometimes cohesion is not needed overtly. There are covert ways of building cohesion and these are more valued in the IELTS exam. Also, over-use of cohesion can be harmful. I can’t see any reference to ‘quite essential’ in the question. Please simply connect the dots. Do not add your own information. When these animals and plants die, they get decomposed and fossilized into fossils. Factories then extract fuels such as oil, coal, and gas from these fossils. They are then combusted to power transport vehicles such as cars. These vehicles emit pollution through which the carbon dioxide is returned to the atmosphere.

Finally, (There is no final stage in a cycle. Point number 1.) some of the carbon dioxide into in (from) the atmosphere is also deposited into absorbed by the ocean where sedimentation takes place. Hence, the formation of calcium carbonate, which is quite essential for deposited as limestones and shells, occurs.

Alternative with active voice: Oceans also absorb the atmospheric carbon dioxide which, through the process of sedimentation, is deposited as limestone and shells in them.

There is a serious problem in two areas – 1. Cohesive devices 2. Own knowledge (task response).
