Ancient bacteria can live in very extreme environments. often with little or no oxygen. true bacteria can not do this. Ancient bacteria are often found in hot sulfur springs, muddy environments such as mudflats and swamps, and places deep in the ocean where lava and hot water seep through cracks on the ocean floor. But true bacteria are found EVERYWHERE except extreme environments.
because they use chemosynthesis to survive instead of photosynthesis like plants.
Bacteria is a decomposer in the ocean. They break down the final remains of living things. Fungi is also a decomposer in the ocean.
Bacteria CAN live on Earth.
Bacteria.
Certain bacteria live in hydrothermal vents on the ocean floor or in oil reservoirs within Earth at temperatures as high as 250oF.
Bioluminescent organisms are those that produce light. There are bioluminescent bacteria that live in the ocean like those in the genera Vibrio and Photomicrobium.
A Protista can be either anaerobic or aerobic. This is because some of them live at the bottom of the ocean or in hot springs.
