Over the decades local and global ice ages have lowered sea levels. As a result, there is often a decline in marine diversity due

B) Changes in the temperature and salinity of water.

Explanation:

Options:

A) Migration of bottom feeders into the region.

B) Changes in the temperature and salinity of water.

C) Migration of fresh water fish to places near the mouths of rivers.

D) Formation of breeding grounds for various species in the shallow waters.

Sea level changes are among the most relevant issues that our planet is facing due to climate change. This phenomenon impacts the salinity and temperature of the ocean because of the melting of glaciers, and ice sheets. Therefore, melting ice alters the level of salinity of the water which, along with temperature, also effect the density of the ocean water, altering ocean currents and productivity. These impacts alter the distribution, behavior, and ecology of marine organisms.

*Note: The melting of the glaciers and ice sheets - result of anthropogenic climate change - has increased sea level.
