Answer:
Neurotransmitters are released from axon terminals via exocytosis
Explanation:
Dendrite is the receiving part of the presynaptic neuron, while axon is the transmitting part of the neuron. So, after initiation, action potentials travel down axons to the terminals. Action potential travels through the membrane of the presynaptic cell causing the voltage-gated channels permeable to calcium ions to open. Ca2+ flow through the presynaptic membrane and increase the Ca concentration in the cell which will activate proteins attached to vesicles that contain a neurotransmitter (e.g. acetylcholine). Vesicles fuse with the membrane of the presynaptic cell, thereby release their contents into the synaptic cleft-space between the membranes of the pre- and postsynaptic cells (exocytosis of the vesicle's content). Neurotransmitter ACh (from the vesicles) binds to its receptors on the postsynaptic membrane and its binding causes depolarization of the target cell (muscle cell). Depolarization occurs because sodium enters the cell as a result of neurotransmitter receptor binding.

<h3>What is Niche?</h3>
An organism's functional place in an ecosystem is known as its niche.
The biotic elements, which include living components like animals, plants, and fungus, as well as abiotic factors, influence the niche, which is more precisely referred to as the "ecological niche". Abiotic variables are the non-living elements of the environment, including the availability of water, sunlight, and other resources like food and other nutrients.
The distribution and abundance of these elements, as well as how a creature interacts with and changes them, determine its niche within an ecosystem. For instance, when resources are plentiful, a population increases, yet by doing so, the population increases the amount of resources available to predators.

Explanation:
They will be combine together and form a large same land as before some thousand years ago. This will somehow destroy the then population but will start a new civilization with new innovations and ammenities.
