Answer 1

Answer:

1.Holozoic is a mode of nutrition in which organisms eat solid food. ... In this process, an organism ingests the complex organic food material into its body and then digests the food which is then absorbed into the body cells.

b.The process of taking in the food into the body either by swallowing or absorbing it is called the procedure of Ingestion. Amoeba oozes out the pseudopodia to encircle the food and engulfs it forming a food vacuole. This process is known as phagocytosis.

c.Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. It starts in the esophagus where strong wave-like motions of the smooth muscle move balls of swallowed food to the stomach.
