The five main stages of animal nutrition describe the sequential processes through which food is consumed, broken down, absorbed, utilized, and waste is expelled.
The five main stages of animal nutrition are: Ingestion: The process of taking in food through the mouth.
Digestion: The breakdown of food into smaller, absorbable molecules (mechanical and chemical digestion).
Absorption: The movement of digested nutrients into the bloodstream or lymph.
Assimilation: The utilization of absorbed nutrients by the body’s cells for energy, growth, and repair.
Egestion: The removal of undigested and unabsorbed food as feces.
The five main stages of animal nutrition are ingestion, digestion, absorption, assimilation, and egestion.
Concepts Stages of animal nutrition: ingestion, digestion, absorption, assimilation, egestion.

The process of nutrition in animals involves the following steps: Ingestion
Ingestion is the process of taking in food.
Digestion
In this process, the larger food particles are broken down into smaller, water-soluble particles.
There are physical or chemical processes for digesting food.
Absorption
The digested food is absorbed into the bloodstream through the intestinal wall.
Assimilation
The absorbed food is used for energy, growth and repair of the cells of the body.
Egestion
The undigested food is removed from the body in the form of faeces.
This process is known as egestion.

The first step to obtaining nutrition is ingestion, a process where food is taken in through the mouth and broken down by teeth and saliva. Animal digestion begins in the mouth, then moves through the pharynx, into the esophagus, and then into the stomach and small intestine. In order for nutrients to be absorbed for energy, food must undergo chemical and mechanical digestion. Nutrients are absorbed in the small intestine and waste is prepared for elimination in the large intestine. Undigested food enters the colon where water is reabsorbed into the body and excess waste is eliminated from the anus. All three phases of digestive responses to food are managed through enzymatic neural control. The endocrine system controls the release of hormones responsible for starting, stopping, slowing, and quickening digestive processes. These phases can be considered the main stages of animal nutrition, specifically ingestion, digestion and absorption, and elimination.

The various steps of nutrition in animals are: Ingestion: The process of taking in of food into the body is called ingestion.
Ingestion of food in humans is done with the help of the buccal cavity.
Digestion: The process where conversion of food into soluble form occurs.
Absorption: The nutrients from the digested food are absorbed in the small intestine with the help of finger-like projections called villi.
Assimilation: The absorbed nutrients are transported via the blood vessels to the different organs, to be utilised for different life processes.
Egestion: The process of removal of faecal matter through the anus is called egestion.

Nutrition in Animals take place in 5 steps Ingestion Digestion Absorption Assimilation Egestion.
Ingestion: The process of taking food into the body is known as Ingestion.
Digestion: The process in which the food containing large insoluble substances is broken down into smaller water soluble units is known as digestion.
Absorption: The process in which digested food passes through the intestinal wall into the bloodstream is called absorption.
Assimilation: The process in which absorbed food is taken in by the body cells and used for energy , growth and repair is known as assimilation.
Egestion: The process by which leftover food waste is removed from the body is known as egestion.

The five steps which occur in the process of nutrition in animals are Ingestion, Digestion, Absorption, Assimilation, Egestion.
Ingestion is the process by which food is taken inside, then chewed and broken down by teeth.
Digestion is the process in which the food is then digested by secretion of certain enzymes and it is then used by the cells for producing energy.
Absorption is the process in which the digested food passes into the bloodstream.
Assimilation is the process in which the digested food moves into the different cells of the body, for energy, growth and repair.
Egestion is the process by which the undigested food is expelled out from the body through excretion.
