Now, consider the following points before you write your answer for this diagram.

Have a look at the title and the picture again and try to determine the tense which you will use in your answer.

Point 1: What tense structure should you use?

There is no use of past or future tenses. So, the answer that you will write should not contain any past or future tense, rather you need to use the present tense in every paragraph you write. If you write any sentence in past or future form in this answer, you will surely be penalized.

Try to write your answer in Present Indefinite Tense. Here are some structures with example sentences:

There + is/are + number + noun + extension

There are 6 stages in the diagram… … .. . .

 Subject + am/is/are + adjective + noun

This is a continuous process.


The diagram shows that it is a non-stop process.

Subject (3rd person plural number) + main verb without s/es + extension

The tadpoles cling to water plants.

Point 2: How many paragraphs should you write?

If you scrutinize the diagram, you can see some interesting things. Look at the color differences and the information on the right-hand side. There are two parts in the diagram; water level and ground level. This means that the life cycle of a frog is divided into two sections, namely ground period and water period. So, you can describe the diagram in two main bodies. In body 1/paragraph 1, you can describe the water phase and in body 2/paragraph 2, you can discuss the ground phase.

Point 3: How to describe the cycle?

Cycle diagrams mainly depict natural processes. In most cases, you will be given such a diagram on environmental issues like the water cycle, pollution, gas movements, animal life cycles etc. The labels in the diagrams will provide you with the necessary information. You have to use the information in your answer. You should try to use the verbs from the information and change the form of the verbs or use synonyms for those verbs in your Writing Task 1 answer. You must not use the same verb over and over again; rather find some suitable synonyms for them. There are different stages which follow an arrow. This makes a sequence for the cycle. You must not miss the sequence when you write your answer. There might be some additional information labeled in the diagram. You should try to use them as well.

Point 4: Word count?

Word count is crucial in IELTS both Writing tasks. So, you should have an idea of how much to write on different writing tasks. Some diagrams may compel you to write more than 200 words because there is so much information to cover. However, writing too many words will not earn you better scores. More than 150 words mean 151 words or more. As you will not get extra marks for the extra words, avoid writing too many words. Try to write some condensed sentences so that you need not to write more words than necessary.

Point 5: Personal opinions? Never!

It will be a dangerous job and will surely cost you marks or score if you provide any opinion, reasons, impacts or effects and solutions if not illustrated in the diagram. Never write them at all. Avoid using any words, linkers or phrases which indicate opinion, reasons, impacts or effects and solutions.

Consider the above-mentioned points and get a great band score.

Now let’s have a look at the model answer.

Model answer:

The diagram describes the different stages in the life cycle of a frog, an amphibian. Overall, the life cycle consists of 8 stages, opening with mating and ending with the development into adult frogs.

The cycle begins with mating between male and female adult frogs in the ground level. The female frogs subsequently lay a large number of eggs on the water, each having an embryo inside. In the next step, these frogspawn hatch from the egg and little tadpoles emerge from them and they cling to water plants. Gradually, these tadpoles grow bigger and start to form various limbs.

The following stage is the transformation of the tadpoles into young frogs where their tails start to become longer than before and the limbs such as gills grow considerably. In the next stage, the tadpoles start to change as their figures become larger in size, and their hind-legs appear. Next, their front legs emerge and during this stage, pulmonary breathing also commences. Thus, their journey on water ends and ground life begins. Afterward, their tails begin to shorten which disappear in the succeeding stage. Finally, the young frogs turn into adult frogs and they are now ready for mating again.

Word count: 198

The lesson itself is good, thanks for sharing. However, there are multiple mistakes in the sample essay, particularly with your relative clauses.
