IELTS Writing Task 1 Question
Life Cycle of a Frog

Common Questions for the Flow chart
1. Graph Type: Flow Chart
2. Title: Life Cycle of a Frog
3. What are the units of measurement? (e.g., percentage, kilogrammes, number of people or periods, amount, %, age, etc.): No specific units; sequential stages of development
4. Who: (e.g., groups, such as three different countries or men or women): Developmental stages of a frog
5. When: (Periods like Jan-Mar or 1999 to 2015): Not specified
6. Where: (Place, e.g., Australia): General (applies to frogs in natural habitats)
7. Topic: The process of frog development from egg to adult
Detailed Process and Observations
Any change over time (such as an increase or a decrease) is a trend.
- Comparison 1: Initial Stage – Eggs
- Details:
- Frog life cycle starts as eggs, floating as frogspawn on water.
- Comparison 2: Transition from Tadpole to Frog
- Details:
- Tadpoles emerge from eggs with small bodies and long tails.
- Body enlarges and legs start to form over time.
- Transformation into a young frog occurs before maturity is reached.
Sample Answer
The flowchart illustrates the stages in a frog’s life cycle, beginning with egg production and concluding with a fully mature adult.
Overall, the process comprises six distinct stages, each marking a transition from one life phase to the next. The sequence begins in water with frogspawn, which eventually grows into a mature frog that transitions onto land.
In the first stage, frog eggs, or frogspawn, float on the lake’s surface. Following this, tadpoles emerge as they hatch from the frogspawn. At this stage, tadpoles possess a small body and a long tail, allowing them to move effectively in water. As tadpoles grow, their bodies enlarge, tails lengthen, and legs gradually develop to enable a future terrestrial life.
Subsequently, the tadpole transitions into a young frog. It develops a broader mouth, larger legs, and a shortened tail but continues to live in water. In the final stage, the mature frog moves onto land, begins breathing air, and loses its tail. The adult frog then seeks a mate to lay eggs, thus restarting the cycle.
