$\huge \mathcal \red {Here \: we \; Go }$

Explanation:

The lining of the alimentary canal has muscles the contract rhythmically so that the food can be pushed down through it easily .This action is known a peristalsis. These movements of muscles help the passage of food through the gut.

In this type of nutrition, organisms obtain complex organic matter in the form of solid food, which is digested and then absorbed into the cells for its utilisation , e.g. Amoeba, frog and human beings.
