The flowchart implies that there are organisms that produce their own organic compounds, but not by using light and not by using inorganic chemical reactions, and are called autotrophs (the box at the bottom of the chart). In other words, the flowchart suggests that there is a subtype of autotrophs, which is also called autotrophs, that are neither photoautotrophs nor chemoautotrophs.stupidness
If that is true, then it would be useful for the article to explain how these organisms produce organic compounds. If it is false, the flowchart should be fixed. —The preceding unsigned comment was added by 75.202.8.114 ( talk) 07:02, 25 December 2006 (UTC). judo is coolo! —Preceding unsigned comment added by 68.37.182.214 ( talk) 23:15, 11 September 2007 (UTC)
"This mechanism is called primary production in the sea." Does that mean that scuba divers talk differently when they return to the boat, or only when they get back to shore? Or are we talking about the language of mermaids? Unfree ( talk) 06:35, 17 February 2008 (UTC)
The article "heterotroph" states (correctly) that all animals are heterotrophic, and the article Fungus states that some fungi may be considered as autotrophs. I reworded the relevant section accordingly. Kolorado ( talk) 20:14, 6 December 2008 (UTC)
The statement "An autotroph can produce its own energy through photosynthesis through the inputs of light, carbon dioxide and H2O." is inaccurate, because autotrophs convert physical energy source into chemical form. Therefore the better statement can be: "An autotroph converts physical energy through photosynthesis using the inputs of light, carbon dioxide and H2O into chemical form". Nagarjunag ( talk) 11:04, 5 December 2010 (UTC)
"They are able to make their own food, ..." is misleading. Food for the plants consists in their nutrients, which are taken from their environment. If they are capable of making then why take it from the environment? Therefore, This statement is not necessary. The rest of the paragraph is OK. I suggest the "They are able to make their own food, and do not need a living energy or carbon source." be removed. -- Nagarjunag ( talk) 11:46, 3 July 2012 (UTC)
I agree with the previous comment and edited the page. I removed the phrase "they are able to make their own food", but left the statement that autotrophs "do not need a living energy or carbon source", which I think is the main point of the sentence. Siegele ( talk) 23:29, 10 July 2014 (UTC)
Despite the number of primary school textbooks this statement can be found in, it is really meaningless: 'They are able to make their own food' 92.14.112.239 ( talk) 00:28, 11 December 2010 (UTC)

-- 74.96.229.43 ( talk) 23:12, 6 March 2017 (UTC)Autotrophs are organisms that are capable of making their own food. They are "self feeders." These organisms make their own food by converting relatively simple inorganic nutrients into more complex, energy-rich, organic forms. Thus, the autotrophs do not need any outside source of organic material. There are two types of autotrophs, divided according to the processes by which they make their food. Photoautotrophs use the process of photosynthesis, while chemoautotrophs use the process of chemosynthesis. Photoautotrophs are far more common, and examples include green plants, algae and some bacteria. This type of autotroph uses photosynthesis to convert the inorganic chemicals, carbon dioxide and water, into the organic sugar glucose, using sunlight as its source of energy. Glucose is the "food" produced by these photoautotrophs. Chemoautotrophs differ from photoautotrophs because they use chemicals from inorganic chemical reactions, rather than sunlight, as their source of energy to produce organic materials. Certain types of bacteria are chemoautotrophs. For example, there are chemoautotrophic bacteria at deep sea hydrothermal vents where there is no sunlight. These bacteria support the entire food web at these great ocean depths through chemosynthesis, since photosynthesis cannot occur due to the lack of sunlight. In a food web, the autotrophs are the producers. They are the base of the food web, and all other organisms ultimately depend upon them for their energy and organic material. Autotrophs are consumed by other organisms, the heterotrophs, passing along organic nutrients and energy. Thus, without the autotrophs, other organisms would not be able to obtain the food or energy needed to survive.
These are two names for the same subject. Although "primary producer" appears to be used more often, it has other possible meanings while heterotroph is unambiguous. Also, most related articles have names like photoautotroph, lithoautotroph, etc. RockMagnetist( talk) 00:00, 21 November 2019 (UTC)
Are methanotrophs categorized as autotrophs or heterotrophs?
Methanotrophs obtain carbon by taking in methane as a gas dissolved in their environment. Chemically, methane is "organic" (see organic compound) but the methane that methanotrophs eat typically is abiotic – ecologically "inorganic" (see organic matter) – produced by geologic processes – does not immediately derive from some organism.
Unlike conventional heterotrophs, methanotrophs can and do survive eating carbon ( methane) that has never been a part of any organism. As a thought experiment, methanotrophs could presumably thrive in a suitably comfortable environment on a methane-rich but originally lifeless planet (think of somewhere warm, deep inside Titan, for example).
So has this already been worked out? Where do the methane-eaters fit in this classification system? And does the categorization discussed in the article need to be re-written so that autotrophs are allowed to eat methane?
