Is it possible that the carbon atoms in your body may have once made up the living tissues of another person or animal in earlier times? this is impossible since carbon can't enter a living system more than once. possible only if you are a cannibal. possible since carbon cycles through the biosphere. highly unlikely since carbon is always tied up in molecules in organisms or minerals?

possible since carbon cycles through the biosphere.

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !

because the light is a great source of energy for the plants to survive. (i hope this )
