Question

Write one similarity and one difference between the nutrition in Amoeba and human beings.

Solution 1

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.

Differences between nutrition in Amoeba and human beings:

Digestion in Humans Digestion in Amoeba
Humans have a mouth and a complex digestive system. Mouth and digestive system are absent in Amoeba.
Digestive juices are secreted in the buccal cavity, stomach, and small intestine. Digestive juices are secreted in the food vacuole.
Digestion of carbohydrates, proteins, and fats starts in separate regions. All the food components are digested in the food vacuole

Solution 2

Similarity: The digestive juices in amoeba are secreted into food vacuole and in human beings the digestive juices are secreted in stomach and small intestine. Then the juices convert complex food into simpler soluble and absorbable substances.

Difference: Amoeba captures the food with help of pseudopodia and engulf it. In human beings food is taken by the mouth.
