Ecological succession is the gradual process by which ecosystems change and develop over time. Nothing remains the same and habitats are constantly changing.
There are two main types of succession, primary and secondary.
Primary succession is the series of community changes which occur on an entirely new habitat which has never been colonized before.
Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat.
Answer:
A neuromuscular junction is a junction between a <em>nerve fiber</em> and a <em>muscle cell.</em>
Explanation:
<em>A neuromuscular junction (or myoneural junction) is a site of chemical communication between a nerve fiber and a muscle cell, is analogous to the synapse between two neurons. </em>
A motor neuron is able to transmit a signal to the muscle fiber, causing muscle contraction upon stimulation by a nerve impulse, the terminal releases the chemical neurotransmitter acetylcholine from synaptic vesicles binding to the receptors, the channels open, and sodium ions flow into the endplate, this initiates the end-plate potential, the electrical event that leads to contraction of the muscle fiber.
