40 POINTS If the sum of all chemical reactions taking place in an ecosystem results in an overall change in free energy of −9732 kJ, which of the following best describes the impact this will have on the ecosystem?

The amount of energy available to do work will increase.

The ecosystem will move away from equilibrium.

The energy given off as heat to the surroundings will decrease.

The entropy of the ecosystem will increase.

How do temperature and salinity affect deepwater currents? they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water.
