The process of utilization of food by an animal to obtain energy for growth and development is known as nutrition. Plants make their food themselves but animals cannot. Hence, animals depend directly or indirectly on the plant.
There are seven main classes of nutrients that the body needs. These are carbohydrates, proteins, fats, vitamins, minerals, fibre and water. It is important that everyone consumes these seven nutrients on a daily basis to help them build their bodies and maintain their health. Deficiencies, excesses and imbalances in diet can produce negative impacts on health, which may lead to diseases.

Hatch. (Science: ornithology) to produce young; said of eggs; to come forth from the egg; said of the young of birds, fishes, insects, etc. Crosshatching is an extension of hatching, which uses fine parallel lines drawn closely together to create the illusion of shade or texture in a drawing.

The food vacuole or digestive vacuole is a membrane-bound cell organelle (as in an amoeba) associated with a digestive function. They take up the food material by the process of phagocytosis and the ingested food is digested by food vacuole.
Gaurav Seth 5 years, 4 months ago
- The food gets trapped inside food vacuole, into which digestive juices are secreted and convert them into simpler substances.
- The digested food is then absorbed which is required for growth, maintenance and multiplication.
- The undigested food is expelled out by vacuole.

Both Amoeba and humans require energy for the growth and maintenance of their bodies. This energy is derived from the food they eat. The food is in a complex form and is therefore broken down into simple forms by the process of digestion. Both these organisms are heterotrophs as they derive their food from other plants or animals. Difference between nutrition in Amoeba and human beings is gives below:
| Digestion in humans | Digestion in Amoeba | |
| 1. | Humans have mouth and complex digestive system. | Mouth and digestive system are absent in Amoeba. |
| 2. | Digestive juices are secreted in the buccal cavity, stomach and small intenstine. | Digestive juices are secreted in the food vacuole. |
| 3. | Digestion of carbohydrates proteins and fats starts in separate regions. | All the food components are digested in the food vacuole. |
