Repolarization refers to the phase during which the resting potential is restored after depolarization. This means that the inside of the axon membrane becomes negative again compared to the outside.

Repolarization is obtained by the functioning of K+ ion channels. The opening of K+ ion channels allows the K+ to move outside of the axon. Movement of positively charged ion (K+) outside of axon makes the inside negative again and the resting potential is restored.

As a general rule, the lower the npp of an ecosystem, the larger the ranges of its top predators must be. For example, sharks in

Net primary productivity (NPP) can be defined as the amount of energy made available by plants to animals, only at the herbivore leve. The NPP of an ecosystem depends on different factors such as the levels of heat, moisture, nutrients available, competition..If the NPP is low (little available food) than animals sparse (have to move to find it).
