Answer:
Neurotransmitters are released
Explanation:
At a neuromuscular junction, action potential that arrives there causes the release of the acetylcholine into the synapse. This then binds to the receptors that span across the surface of the motor end plate triggering muscle contraction with the release of calcium.
It acts as a transmission passageway for action potential between the end of a motor nerve and a muscle.

Answer:
Primary productivity in an ecosystem is important because it lays the foundation of the food chains and food webs being observed in an ecosystem.
