What is the role of the autotrophs in any food chain? Lesson 5.05
-none of the answers
- Autotrophs make the food that consumers eat
-Autotrophs turn light energy into food energy
-Without autotrophs, heterotrophs would starve

*Multiple choice*

All of the answers are correct...

Explanation:

Autotrophs are defined by their capability to create their own food source through light energy (generally), in turn creating a food source for consumers (heterotrophs).

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
