As we all know, living organisms primarily use two methods to generate energy - photosynthesis and chemosynthesis.
The majority of life on the planet is based on a food chain which revolves around sunlight, as plants make food via photosynthesis. Some types of bacteria are autotrophs. Updated August 17, Chemosynthesis is the conversion of carbon compounds and other molecules into organic compounds.
Carnivores such as octopus consume the snails and mussels. Autotrophs are eaten by herbivore s, organisms that consume plants. At Yellowstone National Park in the U.
Some rare autotrophs produce food through a process called chemosynthesisrather than through photosynthesis. Both chemosynthesis and mechanosynthesis have the potential to construct complex compounds, including new molecules and organic molecules. Chemosynthesis can occur in the presences of oxygen, but it is not required.
