The correct answer is Ingestion - Digestion - Absorption - Assimilation.
The steps that occur in nutrition in animals are Ingestion, digestion, absorption, assimilation, and egestion.
Ingestion is the process in which the food is taken inside through the mouth and broken down by teeth and initial digestion takes place in the mouth by saliva.
Digestion is the process in which food is digested using few enzymes and is used by the cells to produce energy.
Absorption is the process in which cells use the energy from the digested food and helps in building tissues in our body.
Assimilation is the process in which digested food moves into the cells of the body.

Ingestion is the first step in the nutrition process.
The correct order of the processes involved in the nutrition of animals is given below:
Ingestion → Digestion → Absorption → Assimilation → 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. Animals use the organs of their digestive systems to extract important nutrients from food they consume, which can later be absorbed.

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 broken down into small, water soluble molecules 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.

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 method of ingestion is different in different animals.
For example-Bees and hummingbirds suck nectar from plants, a python swallows its prey and cattle feed on grass.
Animals can be divided into the following groups depending upon their food habits:
Herbivores are animals that depend upon plants and fruits for their nutrition.
Carnivores are animals that depend upon other animals for food.
These include organisms that eat both plants and animals.
The different types of nutrition in animals include:
Filter Feeding: obtaining nutrients from particles suspended in water.
Deposit feeding: obtaining nutrients from particles suspended in the soil.
Fluid feeding: obtaining nutrients by consuming other organisms’ fluids.
Bulk feeding: obtaining nutrients by eating the whole of an organism.
Ram feeding and suction feeding: ingesting prey via the surrounding fluids.
This mode of ingestion is usually exhibited by aquatic predators such as bony fish.
