Solution

Amoeba obtains food by Phagocytosis.

Here are the steps of how an Amoeba obtains food:

  1. Detection: The amoeba detects food, usually bacteria, algae, or other microscopic organisms, using its pseudopodia (false feet).

  2. Engulfing: The amoeba engulfs the food particle by extending its pseudopodia around the food particle and enclosing it within a food vacuole. This process is known as phagocytosis.

  3. Digestion: The food vacuole then fuses with a lysosome, which contains digestive enzymes. These enzymes break down the food particle.

  4. Absorption: The digested food is then absorbed into the cytoplasm of the amoeba.

  5. Egestion: The waste materials, which are not absorbed, are expelled out of the body by the process of exocytosis.

So, while phagocytosis is the main method by which an amoeba obtains food, the processes of digestion, absorption, and egestion are also involved in the overall process.
