Why is it said that sunlight provides energy either directly or indirectly to all living thing on earth?
do at least 4 sentences : d

Ultimately, almost all this chemical energy comes from a process called photosynthesis. In this process cells use the energy of sunlight to make a sugar called glucose. Once glucose is in a cell, the cell uses the chemical energy of glucose to produce another chemical called adenosine triphosphate (ATP). Cells then use the chemical energy of ATP to drive the cell's important reactions.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
