Question

what consequences can the release of metals into nearby aquatic ecosystems have?
enhanced aquatic biodiversity
increased fish population
improved water quality
lakes with no fish

Explanation:

Metals released into aquatic ecosystems are often toxic. They can bioaccumulate in organisms, causing harm or death to aquatic life like fish. Enhanced biodiversity, increased fish population, and improved water quality are positive outcomes, which don't align with metal pollution. So metal pollution can lead to lakes with no fish.

Answer:

lakes with no fish
