That honor should probably go to the phytoplankton, minute photosynthetic plants that provide food for krill, and oxygen for the world.
In an energy pyramid, the primary producers are on the lowest level. For a land based pyramid, this would be plant life, for aquatic based, it would usually be algae of some sort.
Producers-- photosynthetic organisms such as plants and blue/green algae.

The producer level pyramid contain the most energy, because the sun has the most energy as we know, and producers<plants> get their energy from it. As the consumers<herbivores> eat the producers<plants> they will only get 10% of their energy, and the one that will eat them<herbivores> will also get only 10% energy.... so on, & so forth... That's why,the producer level pyramid contain the most energy. :D
The trophic levels are stacked in blocks, with the block representing producers forming the foundation of the pyramid. The size of the block is proportional to the biomass in each trophic level. The pyramid owes its steep shape to the loss of 90% or so of the energy with each food transfer in the chain. Found in my BIO 100 book. By Campbell Reece Simon.
The most common energy carrier molecule of living organisms is adenosine triphosphate. It is found in all living cells. It captures energy that is obtained from the breakdown of food molecules.
In cyanobacteria
Genes are found on chromosomes and they determine specific characteristics of the organism. They are hereditary and are transferred from the parent to the offspring.
producers/plants
Ina an energy pyramid, the most energy is found at the bottom or base of the pyramid.
Nutters who believe in pyramid energy. Or if the pyramid is a food chain, producers.
An autotroph is a producer. This means any organism that creates its own food. i.e. Plants, phytoplankton, seaweed.
No, autotrophic producers are always at the bottom of an energy pyramid.
The producers are found at the bottom. They contain the most amount of energy and the energy is transferred to other organisms in the food pyramid. [Consumers].
In an energy pyramid, algae would be the substance found at the bottom trophic level. Algae are eukaryotic organisms, and can be unicellular or multicellular.
At the bottom. The amount of energy being passed on decreases as the pyramid goes up. For example, if the pyramid had 5 flowers on the bottom, 3 rabbits in the middle, and a hawk on top, the most energy would be with the flowers, and least passed on to the hawk.
The bottom of the food pyramid (plants mostly) have the greatest amount of energy available. The best argument for vegetarianism I ever heard.
Bottom level. The producers.
Generally, the lowest open one.
