Answer: is constant
Explanation:
In order to analyze the velocity of the stars within a galaxy, the <u>galaxy rotation curves</u> (developed by the American astronomer Vera Rubin) are used. These graphs are elaborated as a scatter diagram in which the orbital velocity of the stars present in a galaxy is represented on the Y axis and the distance of these stars to the center of the galaxy on the X axis.
Thanks to this diagram, it has been possible to observe a characteristic behavior in the rotation speed of the stars (and gas) present in the galaxies, which differs from the rules of the orbital movement of the planetary systems postulated by Newton and Kepler.
This means that in these galaxy rotation curves it has been observed that the rotation speed of stars and gas is "constant", regardless of the distance to the center of the galaxy. This discrepancy and these results were then used to demonstrate the existence of dark matter in the universe.

Explanation:
Supporting services are referred to as ecosystem services whose requirements are of high importance to the production of all other ecosystem services.
There are lots of ways which human benefits from nature. These benefits can be referred to as ecosystem.
Of option a to d, only option c fits the description above.
Nutrient cycle or recycling nutrients in an ecosystem is very important because it links all organisms whether living or not, together.
It links the living organisms with living organisms, living organisms with the non-living organisms and non-living organisms with non-living organisms.
