The bacteria can turn chemicals like hydrogen sulfide and methane into food.
This way of producing food is called chemosynthesis because the bacteria make food from chemicals, not light. These bacteria provide food to their hosts, allowing the invertebrate host to live and thrive in places no other animals could. Of course where you find worms and clams, you find predators. These ecosystems are home to all sorts of familiar life: In fact, the organisms that live in hydrothermal vents on opposite sides of the planet are more related to each other than their cousins at the surface.
These mussels look like they are growing along the coast at sea level, but the "shore" they live next to is an underwater lake. These special bacteria are the basis of a whole ecosystem one of the few we know about that exists without needing light. These habitats are so unique they could possibly be considered their own biome. Additional images via Wikimedia Commons.

Tube worms by Charles Fisher. In some symbiotic relationships, one of the organisms benefits but the other is harmed. An example of this is a tapeworm in a human. The tapeworm gains nourishment, while the human loses nutrients.
In other symbiotic relationships, one of the organisms benefits and the other is neither helped nor harmed.
Deep-Sea Hydrothermal Vents
An example of this would be an orchid growing on a tree. Symbiosis can occur between any two kinds of organisms, such as two species of animals, an animal and microbes, a plant and a fungus, or a single-celled organism such as a protist and bacteria. In other cases, it is very difficult. The algae live inside the coral polyp and perform photosynthesis, converting energy from the sun and carbon dioxide into organic matter and chemical energy.
In the process, they give off oxygen and other nutrients that the coral needs to live. The coral polyp provides its zooxanthellae with carbon dioxide, shelter, and some nutrients. Mutualistic relationships also occur in the deep ocean, between microbes and a wide range of animals including corals, tubeworms, and mussels.
Many of these are found at cold seeps or at hydrothermal vents. Sunlight cannot penetrate into the deep ocean, so the organisms that live there cannot do photosynthesis.
They must rely on a different source of energy. At cold seeps and hydrothermal vents, there are many chemicals that microbes can use to create food and energy. Denitrifying bacteria use nitrate compounds as their source of energy. In the process, they break these compounds down into forms that plants and animals cannot use. This means that denitrifying bacteria can be a very big problem for plants and animals — most plant species need nitrates in the soil in order to produce essential proteins for themselves, and for the animals that eat them.
Denitrifying bacteria compete for these compounds, and can deplete soil, resulting in limited ability for plants to grow. These bacteria are very beneficial to ecosystems, including human agriculture. They can turn nitrogen gas — which makes up most of our atmosphere — into nitrates that plants can use to make essential proteins. Historically, fertility issues and even famine have happened when soil became depleted of nitrates due to natural processes or overuse of farmland.
Many cultures learned to keep soil fertile by rotating nitrogen-consuming crops with nitrogen-fixing crops. The secret of nitrogen-fixing crops is that the plants themselves do not fix nitrogen: Modern fertilizers are often made of artificial nitrates, like those compounds made by nitrogen fixing bacteria.
But modern methods of genetic and biochemical analysis have revealed that there are important chemical differences between the two, with archaeabacteria using many chemical compounds and possessing many genes not found in the bacteria kingdom.
Only archaeabacteria species can combine carbon dioxide and hydrogen to produce methane. Methanobacteria live in a variety of environments — including inside your own body! Methanobacteria are found at the bottom of the ocean, in swamps and wetlands, in the stomachs of cows — and even inside human stomachs, where they break down some sugars we cannot digest in order to produce methane and energy.

Once thought to be a sub-type of bacteria, modern analysis has revealed that archaeabacteria are an entirely different lineage from modern bacteria. Bacteria — A modern kingdom of prokaryotes.

Electrons are passed through a series of proteins, which harvest their energy to produce life-giving molecules such as ATP. Which of the following is NOT true of chemosynthesis?
It is the process of using energy from chemicals to create organic compounds. It cannot be completed without energy from sunlight. It uses an electron transport chain to extract energy from electrons. It requires both a starting carbon compound, and a source of chemical energy. Answer to Question 1 B is correct.
Chemosynthesis does NOT require energy from sunlight.
