Desnitrificación

The transcript explains how denitrifying bacteria in the soil convert nitrates into atmospheric nitrogen, preventing excess nitrates from accumulating. This process is crucial to avoid nitrate contamination in groundwater, which can harm aquatic ecosystems.

What role do denitrifying bacteria play in the nitrogen cycle?

How do denitrifying bacteria contribute to the conversion of nitrates?

Why is it important to prevent excess nitrates from accumulating in the soil?

What can happen if too much nitrate contaminates groundwater?

In what ways can nitrate contamination affect aquatic ecosystems?
