I have heard that the figure is around 10% efficient.
That's true for plant photosynthesis.
That true for herbivores.
That's true for carnivores.
I read a very interesting book that used this figure to explain how many square feet of land are required to support a plant.
And thus how many square feet of land are required to support an herbivore (that feed on plants).
And thus how many square feet of land are required to support a carnivore (that feed on herbivores).
And thus how many square feet of land are required to support a human (that preys on carnivores).
The land space requirement gets high pretty quickly.
It's a real pyramid thing.
