The diagrams below show the life cycle of the silkworm and the stages in the production of silk cloth.
Sample Response
The givenyielded process charts illustrate the silkworm life cycle and the stages of silk cloth productioncloth production.
Overall, it can be clearly seen that this is a cyclicalcyclonic process and hashave four different stages, which run from eggs to a moth before repeatingstart with eggs and end with a moth.
In the first stage, the cycle begins with eggsthe silkworm is eggs, and the female moth lays eggs on a leaffemale moth gives birth on a leaf which hatch into silkworm larvae after 10 dayswhich took 10 days to silkworm larva. In the following stage, the silkworm larva's main sourcethis silkworm larva main source of food is mulberry leavesis a mulberry leaf. In the third stage, the silkworm larva feeds on mulberry leaves for approximately 4 to 6 weekssilkworm larva needs to 4 to 6 weeks approximately for silk threads. The side of the silk thread is known as a larva which requires 3 to 6 days for the next stage.
In the nextfinal stage, the larva spends 3 to 8 daysthe cocoon needs 3 to 6 days spinning silk thread around itselffor becoming silk thread. In subsequently, 16 days are required for growing up, and it becomes a moth. This is a cyclical life cyclelife cycle or cyclonic process; thus, later, the moth lays eggssome period later moth put eggs and the cycle begins againlater process is same.
Why this response received Band 5.0
The response identifies the cyclical nature of the silkworm's life and follows its broad sequence, which gives the reader a basic framework. However, it omits the silk-cloth production process requested in the task and contains confused stage descriptions and inaccurate timings, including 3–6 rather than 3–8 days. The priority is to cover both processes fully, verify every transition, and rewrite unclear sentences in accurate grammatical English.
IELTS Writing Criteria Scores
Task Achievement
A basic lifecycle overview is given, but the cloth-production process is entirely omitted and several stages and durations are reported inaccurately.
Describe both diagrams and report the sequence precisely: eggs hatch after 10 days, larvae feed for 4–6 weeks, cocoons form after 3–8 days, and moths emerge after 16 days.
Coherence and Cohesion
The response broadly follows the lifecycle order, but repetition, unclear referencing, and awkward linking frequently disrupt progression.
Organise each process in a separate paragraph and use simple chronological links that clearly identify the subject of every stage.
Lexical Resource
Some relevant process vocabulary is attempted, but inaccurate choices and collocations such as "cyclonic process" and "gives birth on a leaf" reduce precision.
Use established process terms such as "cyclical," "lays eggs," "hatches into larvae," and "forms a cocoon."
Grammatical Range and Accuracy
Frequent errors in agreement, articles, verb forms, and sentence construction sometimes make the intended relationships difficult to understand.
Build each stage with a clear subject and finite verb, then check tense and subject–verb agreement sentence by sentence.
