I think it’s A (which is disease)
The ocean absorbs more co2
During an El Nino, warm water gathers along the West coast of South America, so the nutrient rich water is no longer being upwelled. keeping in mind that cold water sinks and warm water rises, usually the warm water near coastal regions would not be full of nutrients compared to the cold water where the nutrients fall. therefore, more fish will be located or migrate to areas of this nutrient rich cold water instead. So, many fishermen would not have high yields of fish ultimately affecting their way of life and money. also a lot of these fish that remain at the surface would not be as healthy or nutrient rich.
hope that helps! :))
A cephalopod is a predatory-like mollusk of the large molluscan class of Cephalopodan animals. This includes cuttlefish, octopus, squid, and/or nautilus. They are animals that live in the ocean. Additionally they eat foods like fish and jellyfish on regular and customary occasions. They sometimes possess cannibalism by eating their own species, which is absolutely crazy. Anyways, I hope that this has helped you today.. :)
