An autotroph is an organism the can develop its very own food making use of light, water, carbon dioxide, or other chemicals. Because autotrophs produce their very own food, they space sometimes referred to as producers.Plants room the most familiar type of autotroph, however there are many different kinds of autotrophic organisms. Algae, i beg your pardon live in water and also whose larger develops are recognized as seaweed, is autotrophic. Phytoplankton, small organisms the live in the ocean, space autotrophs. Some types of bacteria space autotrophs. Most autotrophs usage a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sunlight to transform water from the soil and also carbon dioxide from the air into a nutrient dubbed glucose. Glucose is a kind of sugar. The glucose provides plants energy. Plants also use glucose to do cellulose, a problem they use to grow and build cabinet walls.All plants with green leaves, from the tiniest mosses come towering fir trees, synthesize, or create, their own food v photosynthesis. Algae, phytoplankton, and also some bacteria additionally perform photosynthesis.Some rarely autotrophs create food with a procedure called chemosynthesis, fairly than v photosynthesis. Autotrophs that perform chemosynthesis do not use power from the sunlight to create food. Instead, they make food using energy from chemical reactions, frequently combining hydrogen sulfide or methane v oxygen. Organisms that usage chemosynthesis live in extreme environments, where the toxic chemicals required for oxidation space found. For example, bacteria life in active volcanoes oxidize sulfur to develop their own food. In ~ Yellowstone nationwide Park in the U.S. States of Wyoming, Idaho, and also Montana, bacteria qualified of chemosynthesis have been discovered in hot springs.Bacteria the live in the deep ocean, near hydrothermal vents, likewise produce food through chemosynthesis. A hydrothermal vent is a narrow crack in the seafloor. Seawater seeps down with the crack right into hot, partially melted rock below. The boiling-hot water then circulates earlier up right into the ocean, loaded v minerals native the warm rock. This minerals incorporate hydrogen sulfide, which the bacteria usage in chemosynthesis. Autotrophic bacteria that produce food v chemosynthesis have also been discovered at locations on the seafloor dubbed cold seeps. At cold seeps, hydrogen sulfide and methane seep up from in ~ the seafloor and mix through the ocean water and also dissolved carbon dioxide. The autotrophic bacteria oxidize this chemicals to produce energy.

Autotrophs in the Food ChainTo define a food chain—a description of which biology eat which various other organisms in the wild—scientists group organisms into trophic, or nutritional, levels. There are three trophic levels. Due to the fact that autotrophs perform not consume other organisms, they space the an initial trophic level. Autotrophs are consumed by herbivores, organisms that consume plants. Herbivores are the second trophic level. Carnivores, creatures that eat meat, and omnivores, creatures the eat all varieties of organisms, are the 3rd trophic level. Herbivores, carnivores, and omnivores space all consumers—they consume nutrients fairly than making your own. Herbivores are major consumers. Carnivores and also omnivores are secondary consumers.All food chains begin with some kind of autotroph (producer). For example, autotrophs such as grasses flourish in the Rocky Mountains. Mule deer space herbivores (primary consumers), which feed on the autotrophic grasses. Carnivores (secondary consumers) together as mountain lions hunt and consume the deer.In hydrothermal vents, the food chain’s producer is autotrophic bacteria. Primary consumers such as snails and mussels consume the autotrophs. Carnivores such as octopus consume the snails and also mussels.An increase in the variety of autotrophs will generally lead to rise in the variety of animals the eat them. However, a decrease in the number and variety of autotrophs in one area can devastate the whole food chain. If a wooded area burns in a forest fire or is cleared to develop a shopping mall, herbivores such as rabbits can no longer find food. Several of the rabbits might move to a far better habitat, and some may die. There is no the rabbits, foxes and other meat-eaters the feed ~ above them also lose their food source. They, too, must move to survive.
