Erosion can lead to poor water quality and affect plankton populations. When soil erodes into water bodies, it carries pollutants like sediment and chemicals, harming water quality. Murky water due to erosion can block sunlight, impacting plankton, which rely on sunlight for growth. Excess sediment can also suffocate plankton and their habitats. Reduced plankton populations can disrupt the aquatic food chain, affecting fish and other organisms, ultimately impacting the ecosystem's balance. Addressing erosion is crucial to maintaining healthy water quality and sustaining aquatic life.
