$4.$ The following system is at equilibrium. Determine each component of the total soil water potential in energy$/$volume and energy$/$weight at the points indicated $\backslash (($A$,$ B$,\backslash$ldots$)\backslash ).$ If a component is zero, state why.

$5.$ Refer to Problem$\backslash$# $4.$

a$.$ Consider a microorganism at point A in the loamy sand. Assuming the cell wall of the microorganism is semipermeable, what osmotic $($solute$)$ potential is necessary within the cell to avoid loss of cellular fluid to the soil water? You may assume that osmotic adjustment of the cellular fluid is the only defense against lower water potentials outside of the cell.

b$.$ Using the $\backslash (\backslash$theta$(\backslash$mathrm$\{$h$\})\backslash )$ parameters for the soils listed in Problem $3,$ calculate the water content at Point A and Point B in the figure.

c$.$ Suppose the microorganism at point A has had enough of fighting the water robbing forces in her loamy sand home and dreams of moving to a wetter environment. Her life coach recommends she follow her dreams so she packs up and moves to the wetter soil$(?)$ at position $\backslash ($ B $\backslash )($the silt loam$).$ What cellular solute potential is necessary to prevent dehydration in the new home?

I solved problem $4.$ The Tnot is $-39\mathrm{.}92$ M and I came up with $-3\mathrm{.}92*10$M$^5$ J$/$M$3$ from the Snot and Anot
