	The major action by which amoebas consume matter is through a process known as phagocytosis. When an amoeba encounters a particle of food, it responds by surrounding the particle with its various pseudopods, creating a vacuole of the food within its cytoplasm, and digests it with enzymes before releasing the processed material into its environment. Amoebas consume a variety of things, ranging from algae, bacteria, other [[protozoa]] to dead or decaying matter.[4] Protozoan amoebas are responsible for the consumption of massive amounts of bacteria. The growth of these protozoan amoebas in response to bacterial growth is thought to assist in the [[Nutrient Cycling\|nutrient cycling]] and brings nutrients such as nitrogen from decaying matter closer to the root systems of plants.

	Amoebas, amoebae, or amoeboids is a generalised terminology that refers to a particular type of motile organism. Amoebas are eukaryotic cells or organisms composed of a single cell that modify their shape as a means of motile action. These types of organisms are found in [[protozoa]], fungi and animal lineages.[1] Amoebas are found in abundant numbers across the planet, either in a hard outer shell, known as “testate” or “naked” without one.

	Amoebas, across their multitude of taxonomic distributions, vary greatly in their anatomical morphologies. Different species of amoebas that live in different environments have pressures to survive that require unique solutions. Some amoeba, known as testate amoeba have a hard outer shell with which they protect themselves from harm. These shells vary greatly based on species, and can be made of a multitude of substances containing silica, calcium, chitin, sand grains and diatoms. [2] The osmotic potential of water in an amoeba is subject to high variability in freshwater systems, and as such amoeba in this environment require the use of a contractile vacuole. This organelle can absorb or release water as needed to maintain stable conditions. [3]		Amoebas, across their multitude of taxonomic distributions, vary greatly in their anatomical morphologies.

	The many different types of amoeba move through a structure known as a pseudopod, which means “false foot.” These are bends of the plasma membrane which allow the cytoplasm of a cell to spill into a particular direction, and then serve as an anchor to pull the rest of the cell in the desired direction. The action of the plasma membrane is controlled by actin filaments, similar to how our muscles flex. [3] These pseudopods can take on a myriad of forms, ranging from branching filamented protrusions, bloblike lobes or thin tapering points.
