What would happen to your food web of the aquatic plants dided out because of pollution?

If aquatic plants were to die out due to pollution, it would significantly disrupt the food web. These plants, as primary producers, form the foundation of the ecosystem by providing oxygen and serving as food for herbivores like fish and insects. Their disappearance would lead to a decline in herbivore populations, followed by a ripple effect up the food chain, ultimately threatening the survival of predators and reducing biodiversity. Additionally, the loss of plants would result in increased water temperatures and reduced water quality, further harming aquatic life.
