Three Species of Grasshoppers Are Found in a Transect: 10

Multiple Choice

Three species of grasshoppers are found in a transect: 10 of species A, 15 of species B, and 25 of species C. What is the Shannon diversity index of this transect? (Note: * = times, and ln (x) is the natural logarithm of x.)

A) [0.1 * ln (0.1) ] + [0.15 * ln (0.15) ] + [0.25 * ln (0.25) ]
B) [10 * ln (10) ] + [15 * ln (15) ] + [25 * ln (25) ]
C) The negative of { [10 * ln (10) ] + [15 * ln (15) ] + [25 * ln (25) ]}
D) The negative of { [0.1 * ln (0.1) ] + [0.15 * ln (0.15) ] + [0.25 * ln (0.25) ]}
E) The negative of { [0.2 * ln (0.2) ] + [0.3 * ln (0.3) ] + [0.5 * ln (0.5) ]
