The average size of a living organism on a planet is inversely proportional to the net downward force exerted on the organism. This is the reason that large planets with high levels of gravitational force typically harbor organisms of the smallest sizes. However, a recent study concluded that Xandar, one of the larger planets with a large gravitational force, if habitable, would create an ecosystem that would breed extremely large organisms.
Which statement below best explains the contrast above?
A. Calcium deposits found in the water of Xandar will lead to stronger bones of the organisms.
B. Nidavellir, a planet 5% larger than Xandar, has shown evidence of supporting extremely large organisms.
C. Xandar is covered with nitrogen, the primary content in fertilizer, and hence will support the growth of rich flora.
D. Since Xandar is completely covered in water, the buoyant force of water will counter the gravitational force, reducing the overall net force acting on the organism.
E. Scientists claim that Xandar will support the growth of smallest 4-legged micro-organism ever seen.
