$N(d)=115(0.90)^{d}$
The function $N$ defined above can be used to model the number of species of brachiopods at various ocean depths $d$, where $d$ is in hundreds of meters. Which of the following does the model predict?
Difficulty: Medium
A: 

For every increase in depth by 1 meter, the number of brachiopod species decreases by 115.

B: 

For every increase in depth by 1 meter, the number of brachiopod species decreases by 10%.

C: 

For every increase in depth by 100 meters, the number of brachiopod species decreases by 115.

D: 

For every increase in depth by 100 meters, the number of brachiopod species decreases by 10%.
