Al-Jahiz
al-Jāḥiẓ (الجاحظ) (full name Abū ʿUthman ʿAmr ibn Baḥr al-Kinānī al-Baṣrī أبو عثمان عمرو بن بحر الكناني البصري) (born 776, in Basra – December 868/January 869) was an Arab prose writer and author of works of literature, Mu'tazili theology, and politico-religious polemics.

Autotroph
An autotroph ("self-feeding", from the Greek autos "self" and trophe "nourishing") or producer, is an organism that produces complex organic compounds (such as carbohydrates, fats, and proteins) from simple substances present in its surroundings, generally using energy from light (photosynthesis) or inorganic chemical reactions (chemosynthesis).

Chemosynthesis
In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or methane as a source of energy, rather than sunlight, as in photosynthesis.
