Open Ended

Write the main systems that take a role in animal nutrition.

Multiple Choice

What is the role of the digestive system in the process of animal nutrition?

• Taking food inside the body and process it through four stages: ingestion, digestion, absorption and elimination. 

• In charge of transporting nutrients and waste produced in the digestion process. 

• Expels remaining waste and toxic substances produced in the nutrition process.

• Takes in oxygen and expels Carbon dioxide. Such oxygen is used by the cells to convert the food we eat into energy in a process called celular respiration.

​​Digestion in amoeba

​

​Amoeba is a single celled organism found in pond water. The cell has a cell membrane, cytoplasm and a nucleus. The cytoplasm has many bubble like vacuoles. The cell has finger like projections called pseudopodia or false feet which helps it to move and capture food.

​ When amoeba comes near food particle, pseudopodia is produced around the food particle. The food particle is trapped in a food vacuole. In the food vacuole the food is digested by digestive enzymes and absorbed. The undigested waste is then sent out by the vacuole.

Multiple Choice

The finger-like outgrowths of Amoeba help to ingest food. However, the finger-like outgrowths of human intestine help to:

• Absorb the digested food.

• Produce acids

• Move food along the tract

• All of the above
