The thermocline relates to the stratification of water in a body of water, such as an ocean or lake. Colder and more saline water tends to sink to the bottom layers, with shallower layers being warmer and less saline. Phytoplankton need to occupy the shallower layers as they need sunlight for photosynthesis. However, they also need nutrients to grow, and these nutrients typically sink to the bottom layers. One important nutrient that limits phytoplankton growth in the ocean is iron (Fe). Sometimes the thermocline can break down due to upwelling, wind or other forces, and cold, nutrient-rich water will rise to the shallower layers. This will result in a phytoplankton bloom. Interestingly, some scientists have debated 'seeding' the ocean with iron to try and increase phytoplankton growth as a way to capture atmospheric carbon.

Above 380C and below OoC the rate of photosynthesis decreases. Propose a hypothesis to explain why this occurs.
Effectus [21]

<u>Answer:</u>

<em>Enzyme activity decrease at these temperatures. </em>

<u>Explanation:</u>

Photosynthesis is facilitated by the action of various enzymes and involves light and dark reactions.  In <em>light reactions chlorophyll absorbs sunlight and creates ATP AND NADPH</em>. In dark reactions carbon is fixed using the <em>ATP and NADPH. </em>

The efficiency of all these activities depends on the activity of enzymes which depends on the temperature. The optimum temperature range where the enzyme activity is optimal is about <em>10°c - 20°c</em>. At low temperatures and high temperatures enzyme activity is less efficient.

<em>At a temperature above 38°c and below  0°c enzyme activity decreases. </em>

Along with the spin of earth what causes it magnetic field??
IRINA_888 [86]

It was believed that the magnetic field to be generated deep down in the Earth's core. But the truth is the flow of liquid iron generates electric currents, which produces magnetic fields.

But the truth is no one really knows for certain so the only thing we know is that the spin of the earth is the cause of its magnetic field

Hope this helped :)

Have a great day
