Types of Nutrition  in Animals

The different types of nutrition in animals include:

  1. Filter Feeding:obtaining nutrients from particles suspended in water. Commonly used by fish.
  2. Deposit feeding: obtaining nutrients from particles suspended in the soil. Earthworms use this mode of ingestion.
  3. Fluid feeding:obtaining nutrients by consuming other organisms’ fluids. Honey bees, mosquitos exhibit this mode of food intake.
  4. Bulk feeding:obtaining nutrients by eating the whole of an organism. Example: Python.
  5. 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.

Process of Nutrition in Animals

The process of nutrition in animals involves the following steps:

  1. Ingestion

Ingestion is the process of taking in food.

  1. Digestion

In this process, the larger food particles are broken down into smaller, water-soluble particles.  There are physical or chemical for digesting food.

  1. Absorption

The digested food is absorbed in the bloodstream through the intestinal wall.

  1. Assimilation

The absorbed food is used for energy, growth and repair of the cells of the body.

  1. Egestion

The undigested food is removed out of the body in the faeces. This process is known as egestion.

Feeding and Digestion in Amoeba

The Amoeba is a microscopic organism which is made up of only one cell

The Amoeba has a cell membrane, cytoplasm, a nucleus which is round and dense and small vacuoles which are like bubbles present all over it.

The Amoeba is capable of changing its shape and position on its own.

 It uses false teeth called pseudopodia to take in the food present in the surroundings.

Whenever it wants to intake the food the pseudopodia or finger-like projections come out of its body.

The pseudopodia engulf the food in and the food gets stored in the food vacuoles.

Then it secretes some digestive juices inside the vacuoles that help in its digestion of the food.

The Amoeba then absorbs the digested food and uses it for fulfilling different life processes such as multiplication and growth.

The Amoeba also secretes out waste products or undigested food out of its body. (Olympiads)
