Task 1
The diagram below shows the life cycle of a salmon, from egg to adult fish.
Summarise the information by selecting and reporting the main features and make comparisons where relevant.
Tips:
Write your description of the diagram by answering the following questions:
- Where and in what form do salmon begin their lives?
- When the young salmon emerge from eggs, where are they reared?
- Before swimming to the ocean, where do the young fish migrate to?
- What happens to salmon during their time in the ocean?
- Where do the adult fish then travel to, and why?
- What happens that completes the cycle?
How do you write an overview or summary about a 'life cycle' diagram?
- Count the number of stages in the life cycle.
- Decide on a beginning and an end point in the cycle.
Sample Answer ▼
The provided diagram displays the life cycle of a salmon fish dividing it into different stages, from birth to maturity.
Overall, a salmon fish goes through six* main phases to mature adult from the hatching period. Salmon spend time in three distinct locations during the cycle, moving from river to estuary to ocean and then back upstream.
The initial stage of salmon’s growth cycle takes place in rivers, where the adult fish lay and incubate their eggs. After emerging from eggs, the infant salmon spend their next stage being reared in freshwater. Then, at some point in their development, the fish swim downstream to river estuaries where rearing continues.
Following the estuary rearing period, the maturing salmon migrate to the ocean. Eventually, they grow into fully mature adults who are then ready to procreate for the propagation of the species. Finally, grownup salmons move to spawning areas of rivers to lay eggs and the life cycle of the next generation begins anew.
