B. Serosa
C. Sumucosa

A) mucous

Explanation:

The myenteric plexus is located in which layer of the alimentary canal?

A. Mucous

B. Serosa

C. Sumucosa

Wall of the alimentary canal contains four tissue layers which are

✓ the mucosa

✓ submucosa

✓muscularis

✓serosa.

The mucosa can be regarded as innermost tunic of the wall, which

serves as lines in the lumen of the digestive tract. It contains epithelium, which is an underlying loose connective tissue layer, and it reffered to as " lamina propria" along with thin layer of smooth muscle that is reffered to as" muscularis mucosa" .The myenteric plexus is found in between longitudinal layers as well as circular layer of the muscularis externa. It serves as the one that regulate neuronal intestinal motor function.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
