Where does bacteria get energy?

Answer 1

By feeding on other organisms. Some bacterias are also photosynthetic and are able to produce energy using sunlight. Others are also chemotrophic and are able to produce energy using inorganic chemicals.

Answer 2

Most types of bacteria obtain energy by simply breaking down organic compounds. However, some types of bacteria will obtain energy by simply making it themselves, by the use of carbon dioxide.

Answer 3

Bacteria can get food three different ways:

-Heterotrophs-->get food without making it

-Autotroph-->makes food by using the sun aka photosynthesis

-Autotroph-->makes food from the chemicals in its surroundings aka chemosynthesis

The bacteria will get energy from these foods, but they cannot release it! In order to do that, they have to go through a process known as respiration, a breathing thing. The respiration breaks down the food and releases the energy. This happens in all organisms, including us.

Answer 4

Bacteria can get energy in different ways:

1) Photo-autotrophic Bacteria can use energy from the sun to produce ATP and to reduce certain molecules that can later be used to produce carbohydrates. This entire process from solar energy to carbohydrates is called photosynthesis.

2) Chemo-autotrophic Bacteria can use energy from chemicals such as molecular hydrogen, elemental sulfur, methane, and ammonium etc.

3) Heterotrophic Bacteria obtain energy from other organisms and it is further divided in following types ,Saprobic get energy from dead organic matter , Parasitic obtain from live host .

Answer 5

Bacteria are mainly autotrophic but some are heterotrophic (those kinds being the extremophiles from the kingdom Archaebacteria

Answer 6

They suck the energy in through little holes in their body from anything that they are touching.

Answer 7

it uses energy by breaking down food

Answer 8

Glycolysis is one way.

Answer 9

from water and food :)
