Some bacteria manufacture and absorb their own food, while others must consume substances like living organisms or decaying material through their cell walls. Bacteria break down food in a process called respiration, which for some strains of bacteria requires oxygen to complete.Know More
Many types of bacteria are able to eat a variety of things like milk, meat, oil and gas. Some bacteria live in the digestive tracts of humans and other animals and assist the body by helping to digest food and eating other, harmful bacteria. Escherichia coli, more commonly known as E. coli, is one bacteria that lives in the human body and survives by digesting food, absorbing some of the nutrients and releasing vitamin K. The harmful version of the E. coli bacteria causes people to become sick when ingested.
In order to eat, some bacteria absorb food through their cell walls. Many are autotrophs, meaning they make their own food using things like sunlight, water and soil, similar to the photosynthesis method many plants use. They absorb the food they produce and release oxygen into the air.
Bacteria are also used to make food like cheeses and yogurt. They eat the milk sugars and convert them to lactic acid, with softer cheeses having more bacteria than hard cheese.Learn more about Cells
Bacteria that make their own food are known as autotrophs or producers, and they do this through the process of photosynthesis or chemosynthesis. Most autotrophs use the process of photosynthesis, which usually involves converting carbon dioxide and water into glucose using the sun?s energy.Full Answer >
When an amoeba wants to eat a food particle, it extends a long, variably shaped structure around the item and engulfs it whole. These long structures are called pseudopodia, and amoeba can make and adjust them as necessary to move or capture food. Once inside the cell’s protoplasm, the amoeba’s vacuoles digest the food item.Full Answer >
Archaebacteria obtain food by absorbing resources in the environment as precursors for various energy conversion processes. The type of resources that archaebacteria absorb depends on the type of archaebacteria. Each type of archaebacteria has a specific method for converting resources into energy, as well as residing in different habitats.Full Answer >
Prokaryotic and eukaryotic cells differ in many ways, notably in the structure of their cell walls, the arrangement of their genetic material and their internal arrangement of cellular machinery. Eukaryotes, a group that encompasses all large organisms, also tend to reproduce sexually, while prokaryotes show more variation in reproductive methods.Full Answer >
