The answer is C because it is takeing away part of its habitat which would make it's carrying capacity lower which means they cannot have as big of a population.
I = 200 ua
V = 70 mV
Power = ?
Formula: Power = IV
Solution:
Power = IV
= ( 200 x 10^-6 A ) x ( 70 x 10^-3 V )
Power = 1.4 x 10^-5 Watts
The power that the neuron release is 1.4 x 10^-5 Watts
