So-called 'primary producers', organisms that produce biomass from simple chemical compounds and an external energy source. Plants are primary producers: they produce plant biomass from CO2 and water, using the sunlight as a source of energy. In the ocean, phytoplankton is responsible for most of the primary production. Some organisms use energy sources other than light to produce biomass. Some bacteria, for instance, derive their energy from the oxidation of inorganic chemical compounds (e.g. H2S). In the deep sea, whole communities are supported by this kind of chemosynthesis.
I want infomation about Types of organisms on the basis of food.
plants
Bacteria would always be the first link in a food chain. This is simply because it is so small and is, essentially, everywhere.
producer
the organism links the two food webs and combines them into a larger one. This also means the two food webs are in the same ecosystem or are the same type of ecosystem

The organisms of cat family
Because they use the word 'chain' as a type of metaphor. They use chain as a metaphor because the food keeps on going on and on, as does a chain.
