How would the amount of available energy differ in the trophic level of the mouse compared to the trophic level of the hawk?

a.
Available energy would increase from the mouse to the hawk.
b.
Available energy would decrease from the mouse to the hawk.
c.
Available energy would initially increase from the mouse to the hawk, and then decrease over time.
d.
Available energy would remain the same from the mouse to the hawk.

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.

69 is the correct math for the amino acids

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
