Diagrams and flowcharts
This section looks at the other two possibilities for writing task 1, diagrams
and flowcharts. These tasks usually represent how something is produced or
how something works in either a 
linear process
, which is a series of
sequential steps leading to a production of some kind, such as the process of
making paper, or a 
circular process
, where the first and last steps meet at
some point. An example of this is the lifecycle of an insect.
Diagrams and flowcharts resemble each other in organizing the given steps
and applying the required vocabulary, grammatical range, and structures.

---

However, the main difference between diagrams and flowcharts is that
diagrams are usually illustrated, so the steps involved in a process are
elaborated using pictures, while various steps of a flowchart are usually
described using short phrases or some keywords.
Paragraphs’ organization in this task is quite similar to charts and graphs
discussed in the previous section, a 150-word report in four paragraphs. The
main difference between them, however, is the range of vocabulary and
grammatical structures. In this type of writing, using “
passive voice
” is
highlighted. Similarly, “
non-defining relative clauses
” play a significant role
here as they enhance cohesion and minimize repetition. As there are no trends
or numbers involved here, there is no need to use “specific vocabulary for
trends” any longer, but it is crucial to use 
sequencing words or
phrases
to
signal the beginning of a new step in a process for better cohesion.
