Environmental pollution disturbs the ecosystem. Explain.

Ecosystems are impacted by air pollution, particularly sulphur and nitrogen emissions, and ground-level ozone as it affects their ability to function and grow.Nutrient overloads in aquatic ecosystems can cause algae blooms and ultimately a loss of oxygen, and of life.

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
