The main reason is because they are heavy, and because they don't have to chase their food. They're not predators and their shells give them protection like running away gives protection to other herbivores.

The rocks would be younger the closer you get to the ridge
The Mid-Atlantic ridge is a divergent tectonic boundary in the middle of Atlantic Ocean spanning north to south.
Explanation:
At a divergent boundary, a phenomenon called seafloor spreading occurs as new crust is formed along the ridge. New crust seems to 'spread' from the ridge. Therefore, the farther away from the ridge you get, the older the crust gets. This occurs because magma from the mantle rises to replace the void created by the tectonic plates moving away. The magma rises and cools creating a mountainous ridge long the boundary. Seafloor spreading, however, happens really slowly and the changes are only perceptible over 1000s and millions of years.

I think the correct answer from the choices listed above is the first option. The abiotic component that would most likely change in a shallow ocean ecosystem during upwelling would be an increase in oxygen content. Hope this answers the question. Have a nice day.
