Which phenomenon primarily drives meromictic conditions in certain deep lakes?

💡 Explanation

Chemosynthetic bacterial stratification prevents water mixing, leading to meromictic conditions because persistent density gradients inhibit regular seasonal overturn; therefore, deep layers remain anoxic rather than becoming oxygenated like holomictic lakes.
