The process by which plants capture energy from the sun and store it in the chemical bonds of sugars and other food molecules they make.
Answer:
<h2>A trophic pyramid shows where most of the energy in an ecosystem can be found. Each level is called a trophic level and as you move up trophic levels 90% of the energy is lost</h2>

Because of the presence of both activation and inactivation gates, voltage-gated Na channels can be all of these.
- Sodium voltage-gated channels can be either closed, open, or inactive.
- Voltage-gated sodium channels are closed when at rest. Both an activation gate and an inactivation gate are present in voltage-gated sodium channels.
- Although the inactivation gate is open, the activation gate is closed. This conformation is closed but capable of opening. Some of the activation gates open as a result of membrane depolarization brought on by a stimulus.
- Both the activation and inactivation gates will be opened at this point. As sodium ions enter the cells, nearby activation gates will open.
- A greater amount of sodium will enter the cells as a result, initiating an action potential.
- Both gates open when certain depolarization thresholds are reached. Action potential increases to its maximum as sodium rushes into the cell.
- The inactivation gate will gradually close and the permeability of the membrane to sodium ions will decrease. The channel is now in a state known as "closed but not capable of opening."
- Up until the membrane potential reaches its resting state, this occurs. The channels once more assume the "closed but capable of opening" conformation when resting values are attained.
