Question

What do you mean by producers?

Answer 1

A primary producers converts an abiotic source of energy such as light or the energy in inorganic chemical compounds into energy stored in organic compounds, which is usually accumulated in the form of biomass and will be used as carbon and can be used as carbon and energy source by other organisms such as heterotroph and mixotrophs.

Complete answer:
The photoautotrophs are the main primary producers, converting the energy of the light into chemical energy through the process of photosynthesis, and ultimately builds up the organic molecules from carbon dioxide, an inorganic source. Other categories of producers are chemolithotrophs. Examples- archaea and bacteria (unicellular organisms) that produce biomass from the oxidation of inorganic chemical compounds, these organisms are called chemoautotrophs and frequently found in hydrothermal vents in the deep ocean. Without primary producers, organisms that are capable of producing energy on their own, the earth would be unable to sustain itself. Plants, along with other primary producers, produce the energy that is being consumed and the oxygen they breathe. It is a thought that the first organisms on earth were primary producers located on the ocean floors.

Additional information: Primary production in tropical streams and rivers is basically due to aquatic algae. They are the significant contributor to food webs in tropical rivers. This is displayed by net primary production, a fundamental ecological process that reflects the amount of carbon that is synthesised within an ecosystem.

Note:- Net primary production is the amount of biomass formed by the producers that is available for heterotrophs. Producers with the help of sunlight are able to produce their own food and become Autotroph.
