Choose whether the given statement is true or false.

Amoeba is a microscopic and single-celled organism which feeds on other microscopic organisms.

The given statement is true.

Amoebas are unicellular organisms that belong to the group of protozoa. They are characterized by their flexible shape, which allows them to move and change their shape. They use pseudopodia, which are temporary extensions of the cell membrane, to move and capture prey.

Amoebas feed on other microscopic organisms, such as bacteria and algae, through a process called phagocytosis. During this process, the amoeba extends its pseudopodia to surround and engulf the prey. Once the prey is enclosed in a food vacuole, digestive enzymes are secreted into the vacuole to break down the food into smaller molecules. The nutrients are then absorbed by the cell and used for energy and growth.

Amoebas are important components of aquatic and soil ecosystems, where they play important roles in nutrient cycling and energy transfer. However, some species of amoebas can also cause diseases in humans, such as amoebic dysentery and amoebic meningitis.
