Life on the Earth Depends on Interaction of Gravity, the Cycling

Question

Life on the earth depends on interaction of gravity, the cycling of matter, and the ____.
A)recycling of energy
B)one-way flow of high-quality energy
C)one-way flow of matter
D)destruction of energy
E)consumption of matter

Accepted Answer

Life on Earth depends on the interaction of gravity, the cycling of matter, and the one-way flow of high-quality energy from the sun through ecosystems. Energy flows in one direction from the sun, through living organisms, and eventually dissipates as heat, unlike matter, which cycles through ecosystems.
