The Bur Oak Tree comes from a single seed and can grow to
be 60 feet tall. Students wondered how the Bur Oak Tree gets
the material it needs to grow from a single seed to a tree so
tall. They did some research and learned that trees make
their own food by using the sun's energy to change carbon,
hydrogen, and oxygen into a simple sugar.
26. . Develop a model to show how trees form and use simple sugar to get the energy they need
for life. Use your model to explain how energy flows through the systems as food is broken
down and rearranged.

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?
