Tip of the Day When attempting dense reading comprehension passages, such as the ones that have come in recent CAT papers, it helps to reduce reading speed in order to understand the main idea throughly. This is better than having to re-read the passage after reading the questions. Last year's Question of the day (01-May-11) Phytoplankton are also crucially dependent on minerals. These are primarily macronutrients such as nitrate, phosphate or silicic acid, whose availability is governed by the balance between the so-called biological pump and upwelling of deep, nutrient-rich waters. However, across large regions of the World Ocean such as the Southern Ocean, phytoplankton are also limited by the lack of the micronutrient iron. This has led to some scientists advocating iron fertilization as a means to counteract the accumulation of human-produced carbon dioxide (CO2) in the atmosphere. Large-scale experiments have added iron (usually as salts such as iron sulphate) to the oceans to promote phytoplankton growth and draw atmospheric CO2 into the ocean. However, controversy about manipulating the ecosystem and the efficiency of iron fertilization has slowed such experiments.
Which of the following, if true, will help increase phytoplankton levels in the ocean?
| OPTIONS | | | | | 1) | The atmospheric composition is well balanced, thus there is no excess carbon dioxide. | | | 2) | In a research paper published by a reputed team of professors at Harvard, it is proven that iron fertilization is very efficient, but it tends to kill adjacent flora in large quantities. | | | 3) | In the Southern Ocean, an oil drill has caused the nutrient iron to resurface in large quantities. | | | 4) | Manipulating the ecosystem has a history of causing adverse long-term effects. | | | 5) | Phytoplankton need plenty of temperate waters to survive. |
