Answer:
salt water and fresh water
Explanation:
The estuaries are located on the contact between a fresh water body and saline water body, or rather a place where a river enters the sea. Because of this, the estuaries have a mixture of saline water and fresh water. They are also shallow and warm. The sunlight penetrates to their bottom, and they are rich in nutrients. This results in the estuaries to offer several different living conditions, so there are lot of different species living in them.
At first it will be filled with weeds and insects. In about 5 years, a wider variety of plants will be growing there and larger animals will live there. They are there because of the food and shelter. Then in 100 years, there would be more soil (because of decomposing dead organisms). WIth more soil, bigger plants could grow and larger animals could live.
