Explain the process of nutrition in $Amoeba$.

(N/A) Nutrition in $Amoeba$ occurs through the following steps:
$1$. **Ingestion:** $Amoeba$ captures food particles using temporary finger-like extensions of the cell surface called $pseudopodia$. The $pseudopodia$ fuse around the food particle, forming a food vacuole.
$2$. **Digestion:** Inside the food vacuole, complex substances are broken down into simpler, soluble substances with the help of digestive enzymes.
$3$. **Absorption:** The digested food diffuses from the food vacuole into the surrounding cytoplasm.
$4$. **Assimilation:** The absorbed food is used by the cell for energy, growth, and repair.
$5$. **Egestion:** The undigested waste material is moved to the surface of the cell and thrown out of the body through the plasma membrane.
