Trees and water are considered what

Trees are in the biosphere and are plants and water is the hydrosphere.

it's filtration, but this is an assumption so my apologies if i got this

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
