Autotrophs
Organisms that live in deep-sea hydrothermal vents are an exception as they derive energy from chemical reactions in the absence of sunlight. These organisms, like certain types of bacteria and archaea, use a process called chemosynthesis to convert minerals and chemicals in the vent water into energy for survival.
Organisms that derive their energy from sunlight are referred to as photoautotrophs. They use the process of photosynthesis to convert sunlight into chemical energy that can be used for growth and metabolism. Examples include plants, algae, and some bacteria.
Heterotrophs derive their metabolic energy from consuming other organisms or organic matter as they cannot produce their own food through photosynthesis or chemosynthesis. This is in contrast to autotrophs, which can produce their own food using energy from sunlight or inorganic compounds.
Taking 'chemosynthesis' to be equivalent to 'biochemistry', it occurs [in this case] in two forms: one releases CO2 and the other removes it. A Plant in the Dark needs to respire and consume O2 and sugars to produce Atp - just the same as Animals do. Only in the Light can a Plant or any other Photosynthetic Organism remove CO2 from the Air and release O2 instead, as found in the biochemical process called photosynthesis.
Most producers derive their energy from the sun through the process of photosynthesis, where they convert sunlight into chemical energy. Some producers also obtain energy from geothermal sources, chemical reactions, or other organisms.
Autotrophs
A lot of organisms that thrive in the deepest parts of the ocean rely heavily on chemosynthesis. Chemosynthesis is most commonly seen near thermal vents and involves the biological conversion of 1+ carbon molecules (methane/CO2) and nutrients into organic matter. This is made possible through the oxidation of inorganic molecules such as H2 or Hydrogen Sulfide; these are used as a source of energy, rather than radiation from the sun.
From ocean chemicals
Hydrothermal vents on the ocean floor are a location where autotrophs that derive their energy from chemical compounds can be found. These autotrophs use a process called chemosynthesis to convert hydrogen sulfide and other chemicals into energy.

Deep-sea vent organisms are evidence of chemosynthesis, a process where organisms derive energy from chemicals in their environment instead of sunlight. They are also evidence of the adaptability of life to extreme environments, thriving in high-pressure, high-temperature, and high-toxicity conditions.
Producers obtain energy through photosynthesis, where they convert sunlight into chemical energy. They can also derive energy from chemosynthesis by utilizing chemical reactions with inorganic compounds.
Heterotrophs derive their metabolic energy from consuming other organisms or organic matter as they cannot produce their own food through photosynthesis or chemosynthesis. This is in contrast to autotrophs, which can produce their own food using energy from sunlight or inorganic compounds.
Photosynthetic organisms derive their carbon from carbon dioxide in the atmosphere during the process of photosynthesis. They utilize sunlight to convert carbon dioxide and water into glucose and oxygen.
