D. is the heterotrophism hypothesis, but it is questionable that it is the "strongest" hypothesis. The alternately proposed option is autotrophism, which is the ability of an organism to obtain its own nutrients without relying on other organic materials. The potential advantage of autotrophism is its relatively simpler structure, making a simpler organism viable because it is potentially less complex and "easier to create."

Explanation:

Atmospheric oxygen levels are related to the evolution on Earth and changes in geochemical cycles that involve climate variations.

The presence of O 2 and evolution of oxygen gave new opportunities to the life on Earth. Oxygen levels in atmosphere have fluctuated between 15% and 35% of atmospheric volume, since the start of the Cambrian period.

So, form the starting 200 million years ago, oxygen level stay above 15 percent and the correct option is "B".

Annette [7]

Answer:

B) Changes in the temperature and salinity of water.

Explanation:

<em>Options</em>:

A) Migration of bottom feeders into the region.

<u>B) Changes in the temperature and salinity of water. </u>

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, <u>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.</u> These impacts alter the distribution, behavior, and ecology of marine organisms.

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