El Niño would cause changes in the genetic makeup of organisms

A

Explanation:

El Niño is defined as an abnormal weather pattern caused by the warming of the Pacific Ocean near the equator, off the coast of South America. The sun warms the water near the equator, which can make more clouds and, therefore, more rain. It has detrimental effects on biodiversity leading to its large-scale loss by warmer sea temperatures leading to plankton and fish kills in coastal waters lower sea levels leading to exposure of underwater coral reefs, causing their loss.
