The Earth's systems are all interdependent, which means that A. each system has no influence on the other systems. B. one system can overpower the other systems, causing damage to the Earth. C. each system works by itself to benefit the Earth. D. each system is unique, yet each interacts with the others.

The answer to the question is D. each system is unique, yet each interacts with the others. In an interdependent system, each part of the system works in its own way but interacts with the others. When combined together, all the different systems produce individual benefits but interact with one another to produce a huge benefit for the planet Earth.
