Norepinephrine is a major excitatory neurotransmitter that regulates the release of dopamine, it is a substance used mainly by the sympathetic or orthosympathetic nervous system, it is part of the neurotransmitters, its function is to transmit messages through the nerves to the different components of the body through numerous physiological processes.
The graph will have a sharp curve in upwards manner when the new, larger habitat is found, but than will be followed by slight decrease when the predation increases.
Explanation:
If a population of rabbits finds a new, larger habitat, than the population will experience rapid rise, especially if there isn't high scale predation on them. This will be due to the abundant food resources, but also because of the fast reproduction of the rabbits. The low predation will mean that most of the rabbits will survive, so the numbers will be on the rise.
When the population starts to experience in increase in predation, the situation changes. The larger number of predators means that they would need much more food, so much more rabbits will be killed and consumed by the predators. This will stop the population rise, and it will either stagnate, or most probably it will experience slight decline.

In my opinion mixed layers would be the best choice
Food is chewed and mixed by the teeth and tongue before being rolled into boluses by peristalsis and entering the stomach through the cardiac sphincter. In the stomach, gastric juice contains pepsinogen, which is activated to pepsin, which breaks down proteins in beans into shorter peptides. Finally, food is churned and allowed into the duodenum via the pyloric sphincter muscle. Finally, bile Trypsin breaks down proteins into shorter peptides, and pancreatic juice, which is released by the pancreas, contains pancreatic lipase, which breaks down bean oil into fatty acids and glycerol. When food enters the ileum, where succus entericus is secreted, it contains the enzymes maltase, peptidase, and lipase, which break down the remaining lipids (oil) into fatty acids and glycerol, which are then absorbed through the lacteals of the villi. Maltase breaks down maltose into glucose, which is then absorbed.
The Digestion and Absorption Process
Even before you put food in your mouth, digestion starts. Your body notifies your brain that it is time to eat when you feel hungry. Your body's ability to prepare for eating is influenced by sights and odours. Your brain receives a message when you smell food. The mouth is subsequently instructed by the brain to prepare, and you begin to salivate in anticipation of a mouthwatering meal.
