An amoeba gets energy in the same way that you do - from its food. An amoeba feeds by sending out 'bulges' of its cytoplasm, called pseudopodia, to surround a small food particle eg a smaller protozoan or an alga. The food, together with a small drop of the water is taken into the cell to become a food vacuole. Enzymes are then added to the food vacuole to digest the food. The soluble products of digestion are taken into the cytoplasm and used for respiration or growth. The release of energy from food is called respiration. Usually, the sugar called glucose is used by cells. Respiration usually involves 'burning' the food with oxygen. When this happens water and carbon dioxide are also produced: glucose + oxygen ---> water + carbon dioxide + ENERGY For a number of interesting articles about amoebae with photographs, go to: http://www.microscopy-uk.org.uk/full_menu.html Select Miscape article library, click on the Find icon and enter amoeba into the search box.

The primary sources of energy for an amoeba are organic matter such as bacteria, algae, and other small organisms that it engulfs through phagocytosis. Once ingested, the amoeba breaks down these organic molecules into nutrients like sugars and amino acids to generate energy through cellular respiration.
The food vacuole is formed by the outer membrane of the amoeba after phagocytosis, digestive enzymes then enter the food vacuole which digest the food that was recently taken in by pseudopods.
The small cavity within the cytoplasm of an amoeba that stores food is called a food vacuole. This structure helps the amoeba digest and break down food particles for energy.
The amoebae is an eukaryote, so it uses oxygen for the same reason you do. Oxygen is the final electron acceptor in the process of oxidative phosphorylation that takes place in the mitochondria.
Man evolved over time from the amoeba.

The amoeba finds tiny particles of organic matter, and eats them. All animals get energy in essentially the same way, by eating food. The food can then be used as fuel for the metabolism.

An amoeba uses a food vacuole to digest and break down food particles that it engulfs. The vacuole contains enzymes that help in the process of intracellular digestion, allowing the amoeba to absorb nutrients for energy and growth. Once digestion is complete, any undigested material is expelled from the cell.
