WRITING TASK 1

You should spend 20 minutes on this task.

The diagram gives information about the life cycle of a frog.

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

Write at least 150 words.

The process demonstrates how a frog’s development takes place over time.
Overall, the diagram outlines a sequence of natural developments that ensure the survival of frogs through metamorphosis.
Initially, the cycle starts with an adult frog laying eggs in water. These eggs develop into embryos, which then hatch into tadpoles. The tadpoles cling to water plants and develop external gills for breathing. Following this, their tail keep beacoming longer, followed by the appearance of hindlegs. At this stage, they survive by consuming nutrients stored in their tail.
As the front legs begin to grow, the color of the body gradually changes from black to green. In the next stage, the tails become shorter until it disappeares, marking the transformation into young frog. Eventually, the young frog becomes a fully grown adult, now completely green in color. The entire cycle then repeats itself

Natural Process Diagrams: The Life-cycle of Frogs

The diagram illustrates a frog’s physical development. Overall, the life cycle is long and complex, consisting of 10 stages. It begins when an adult frog lays eggs and concludes when a young frog matures into a fully grown adult.

In the first half of the process, the frog begins life as a tadpole. First, the eggs develop into embryos with the undeveloped tadpole growing inside. When the tadpole is ready, it hatches from the embryo and clings to underwater plants. In the next stage, the tadpole develops gills, which allow it to breathe underwater, and its tail grows longer.

In the second half of the process, the tadpole begins to transition into a frog. Rear legs start to appear at the back of the animal’s body. Then, while sustaining itself on food stored in its tail, front legs begin to grow, and the tail begins to decrease in size. By this stage, the amphibian is more recognizable as a frog than in the previous stages. When the tail has completely vanished, the animal becomes a young frog. In the final stage, the young frog matures into an adult frog, ready to lay eggs and begin the process again.
