Frog
The diagram below shows the life cycle of a frog.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
The diagram delineates a frog’s life cycle. Overall, this cyclical process is comprised of 7 main stages, beginning with mating, followed by the development of tadpoles from frogspawn, and ending with fully-grown frogs.
The process commences with adult frogs mating, resulting in frogspawn from which tadpoles emerge. A typical newly-hatched tadpole consists of only a rudimentary body and a tail. As the tadpole develops, its tail lengthens and becomes more visible, its head bulges and lower limbs emerge with an indication of thighs and toes.
In the remaining stages, as the tadpole matures, it displays clear lower limbs with paddle-shaped feet, a bigger yet more streamlined body, upper limbs with fingers, and sees its tail shrunk when reaching adolescence. The mature form is not indicative of a tail, has longer hind limbs, and shows clear changes in complexion. Adult frogs finally leave the water and venture onto land for mating, and the process repeats.
