The primary impact of marine pollution on food webs is the introduction of harmful substances, such as plastics, heavy metals, and chemicals, which can disrupt the balance of marine ecosystems. Pollutants can accumulate in organisms, leading to bioaccumulation and biomagnification through the food chain, affecting both predators and prey. Consequently, this can lead to declines in biodiversity, altered predator-prey relationships, and harm to species at various trophic levels. Marine pollution ultimately jeopardizes food security and the livelihoods of communities reliant on healthy marine ecosystems, emphasizing the need for pollution prevention and management efforts.
