Trophic levels make up the food chain. All food chains and webs have at least two or three trophic levels. Normally, the maximum trophic levels are four.
The levels are:
1: Plants and algae (producers).
2: Herbivores (primary consumers).
3: Carnivores (secondary consumers).
4: Carnivores that eat other carnivores (tertiary consumers).
However, many consumers also feed at more than one trophic level.
Answer:
<em>The answers are: phrenic nerve, cervical spinal nerve, branches of the cervical plexus, the thoracic, and the root of the lung to reach the diaphragm.</em>
Explanation:
One important branch of the cervical plexus is<u> </u><u><em>the phrenic nerve</em></u>, which is formed primarily from the <u><em> cervical spinal nerve</em></u> and some contributing axons from<u><em> branches of the cervical plexus.</em></u>
This nerve travels trhought <u><em>the thoracic</em></u> cavity to innervate <u><em>the root of the lung to reach the diaphragm</em></u> and its important for breathing.
This question is about the network of nerve fibres that supplies innervation to some of the structures in the neck and trunk.
<span>The binding of acetylcholine to ACH receptors results in the change on membrane of the target cell. Acetylcholine is rapidly removed by enzymatic breakdown.As the brain cells of an Alzheimer patient dies, excess amount of glutamate is released.So
patients with Alzheimer's disease tend to have abnormally depleted levels of acetylcholine and abnormally higher levels of glutamate.</span>
