Please help me with Writing Task 1

Topic: The diagrams below show the life cycle of a species of large fish called Salmon.
Summarize the information by selecting and reporting the main features and make comparisons where relevant.

The diagrams illustrate how salmons grow in three different habitats according to three main development stages.

In the first half of life, salmons spend most of their time in river. A mature salmon lays a batch of several eggs in reeds in the upper river, where the current is slow. After nearly five or six months, the eggs hatch into fries, which is a newborn salmon with a 3-8 cm body length. Fries will then swim downstream to the lower river, where there is fast-flowing current and reside here for four years.

After fully growing into their full size of 12-15 cm, fries, which are now called smolts, will once again relocate to a new habitat - the open sea and live here for approximately five years. Once they reach their sexual maturity, adult salmons, which is now 70-76 cm long, will migrate to their birthplace to spawn, reproducing a new salmon generation.
