“An autotroph is a plant that can synthesize its own food through the process of photosynthesis.”

“In turn, high autotroph productivity begets high consumer productivity, which is positively associated with herbivore diversity.”

“The first parasitic association to evolve between a microbe and an autotroph was probably perthotropic in nature.”

“The kelps are an important group of marine autotrophs that has left little or nothing in the way of a direct fossil record.”

“Since plants and other photosynthetic organisms can produce many of their own nutrition requirements they are known as autotrophs.”

“The base of the pyramid is composed of species called autotrophs, the primary producers of the ecosystem.”
