Electric potential due to a point charge is given by

V = \frac{kQ}{r}

here we know that

Q = charge

r = distance from the charge

V = \frac{9*10^9* 2.2* 10^{-6}}{6.3}

V = 3142.8 Volts

now again by the same equation

V = \frac{kQ}{r}

V = \frac{9*10^9* 2.2* 10^{-6}}{99}

V = 200 Volts

Answer:

C. Energy is used for life processes (e.g. Movement, breathing, etc.)

Explanation:

As we pass from one trophic level to the next, only 10% of energy is transferred from the first trophic level to the next. This is because a lot of energy is lost to the surroundings and rest is utilised by the organism.
