Nutrition In Animals
Write one similarity and one difference between the nutrition in Amoeba and human beings.
Similarity between nutrition in Amoeba and human beings:
Both Amoeba and humans require energy for the growth and maintenance of their bodies. This energy is derived from the food that they eat. The food that they consume is always in a complex form and is therefore broken down into simpler forms by the process of digestion. Hence, both these organisms are heterotrophs.
