Similarities:

- Marine and freshwater ecosystems are water, covering almost 75 percent of the earth's surface.

-The most pervasive problem affecting both freshwater and marine ecosystems is pollution.

-The process of regulating the osmotic pressure on fluids inside an organism is essential to all freshwater and marine species.

Differences:

- Marine ecosystems are more diverse than freshwater ones.

- In marine or seawater, the salinity level, or the concentration of salt is greater, but freshwater is not totally void of it.

- Only 1% of the whole water body on the earth is freshwater, the other 99% is marine water.

Note- I couldn't come up with ones for estuaries, sorry.

This article includes a list of general references, but it remains largely unverified because it lacks sufficient corresponding inline citations. (August 2008)

The three-sector model in economics divides economies into three sectors of activity: extraction of raw materials (primary), manufacturing (secondary), and service industries which exist to facilitate the transport, distribution and sale of goods produced in the secondary sector (tertiary).[1] The model was developed by Allan Fisher,[2][3][4] Colin Clark,[5] and Jean Fourastié[6] in the first half of the 20th century, and is a representation of an industrial economy. It has been criticised as inappropriate as a representation of the economy in the 21st century.[7]

Service output in 2005

According to the three-sector model, the main focus of an economy's activity shifts from the primary, through the secondary and finally to the tertiary sector. Countries with a low per capita income are in an early state of development; the main part of their national income is achieved through production in the primary sector. Countries in a more advanced state of development, with a medium national income, generate their income mostly in the secondary sector. In highly developed countries with a high income, the tertiary sector dominates the total output of the economy.

The rise of the post-industrial economy in which an increasing proportion of economic activity is not directly related to physical goods has led some economists to expand the model by adding a fourth quaternary or fifth quinary sectors, while others have ceased to use the model.
