Abstract

Ocean acidification, driven primarily by the uptake of anthropogenic carbon dioxide (CO2), is emerging as a significant environmental threat, with profound implications for marine ecosystems. This phenomenon, characterized by a decrease in seawater pH, disrupts the chemistry of the ocean, leading to adverse effects on marine life. This
article explores the mechanisms and consequences of ocean acidification, focusing on its impact on marine food web dynamics. We delve into how the altered ocean chemistry affects various trophic levels, from primary producers to apex predators, and discuss the broader ecological ramifications. By examining case studies and recent research, we highlight the interconnectedness of marine organisms and the cascading effects of acidification on biodiversity, species interactions, and ecosystem resilience. The article underscores the urgency of addressing CO2 emissions and outlines potential mitigation strategies to preserve the integrity of marine food webs in the face of ongoing climate change.
