Autotroph is a term used in biology to refer to organisms that are capable of producing their own food. These organisms are unique in that they do not depend on other organisms for their sustenance. They are able to create their own energy using sunlight, water, and carbon dioxide. In this article, we will explore the definition and meaning of autotroph, its origin, and its various associations.
Definitions
Autotroph is defined as an organism that is able to produce its own food using inorganic substances. This process is known as photosynthesis and involves the conversion of sunlight, water, and carbon dioxide into energy. Autotrophs are also referred to as primary producers as they form the base of the food chain.
Origin
The term autotroph is derived from the Greek words “autos” meaning self and “trophe” meaning nutrition. The term was first used in the early 20th century to describe organisms that were capable of producing their own food.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, autotroph is defined as “an organism capable of synthesizing its own food from inorganic substances, using light or chemical energy.” The Oxford English dictionary defines autotroph as “an organism that is able to produce its own food from inorganic substances.”
Associations
Autotrophs are associated with the process of photosynthesis, which is the primary means by which they produce their own food. They are also associated with the concept of primary production, which refers to the amount of organic matter produced by autotrophs in an ecosystem.
Synonyms
Synonyms of autotroph include primary producer, self-nourishing organism, and self-sustaining organism.
Antonyms
Antonyms of autotroph include heterotroph, which refers to organisms that are unable to produce their own food and must rely on other organisms for sustenance.
