Nitrosomonas and iron bacteria are the most common examples of chemoautotrophic bacteria because they are able to produce energy through a chemical process, according to Dr. John W. Kimball. These organisms are unique because they are able to produce the energy they need without photosynthesis.
Most organisms on the earth need photosynthesis to survive and to produce the energy they need to function. Chemoautotrophic organisms do not need these processes because they are able to oxidize the electron molecules that they take in from their own internal environments in order to survive. They do not live on anything other than molecules and are able to sustain themselves through the use of these electrons.
Chemoautotrophic bacteria are at the bottom of the food chain. They do not eat anything or take anything in other than at a molecular level and are essential to the survival of small sea creatures. Chemoautotrophic bacteria are responsible for methane, hydrogen gas and carbon monoxide that are found in the ocean. These gasses are a result of what happens when the chemoautotrophs convert the electrons to energy. Some chemoautotrophs, like the iron bacteria, are responsible for everyday things like the rust-colored stains that are often found on the inside of a toilet tank.Learn More
Algae are a type of plant that usually grows on the surface of still water, such as a small pond, when there is an ecological imbalance. In some cases, algae is able to grow at a rapid rate, potentially spreading across the entire surface.Full Answer >

A community of organisms and their nonliving environment is called an ecosystem. In addition to living organisms, the primary components of an ecosystem are soil, atmosphere, heat and light from the sun, and water.Full Answer >
The work of Thomas Malthus was studied by Charles Darwin. Malthus, an English scholar and social economist, observed that high population growth is controlled by such natural catastrophes as famine and disease. Darwin applied this observation to animal populations and formulated his theory of natural selection.Full Answer >
