In dead zones resulting from eutrophication, animal life is absent due to the lack of oxygen

Explanation:

The eutrophication is a process of enrichment of a water body by minerals and nutrient due to excessive growth of algae. Contamination of a water body with organic nutrients increases the biological oxygen demand and the chemical oxygen demand of the body.

This is because of the growth of a large amount of microbes including the algae in the water body that results in the reduction of oxygen in the particular water body marking a dead zone.

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.

b. climate change will cause an increase in biodiversity of all ecosystems.
