Which statement describes ALL primary producers? Primary producers generate high-quality energy in an ecosystem and generally high in numbers but they can be some time fewer in the number than top trophic level consumers. Primary succession occurs in essentially lifeless areas—regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier.
