| 11. | Highly organic-rich siliceous shales were deposited during this time in anoxic conditions on the sea bottom.
|
| 12. | Consequently, varves commonly form under anoxic conditions.
|
| 13. | Many species of bacteria can transform arsenite to arsenate in anoxic conditions by using arsenite as an electron donor.
|
| 14. | Species sensitive to anoxic conditions are replaced by fewer hardier species, reducing the overall variability of the affected area.
|
| 15. | The color and acidity of the water is due to the acidic organic anoxic conditions which limits plant growth.
|
| 16. | A few animals, including some turtles, can survive anoxic conditions by slowing their heart rates, and their metabolism, way down.
|
| 17. | Plants usually rely on soil primarily for support and water ( in quantitative terms ), but also obtain anoxic conditions.
|
| 18. | The oil shale is thought to have been the result of slow deposition of planktonic algae . under anoxic conditions.
|
| 19. | Algal blooms creating anoxic conditions and cannibalism caused by high density stocking of ponds are also challenges to koura farmers.
|
| 20. | When oxygen concentrations become low, anoxic conditions may develop which can decrease the ability of the water body to support life.
