What does a pyramid of net production look like in a real ecosystem, and what are the trophic efficiencies? the pyramid below represents the data collected from h. t. odum's work on the silver springs ecosystem in north-central florida. (note that odum used the units kilocalories [kcal] instead of joules [j].) drag the labels to the pyramid to indicate the trophic efficiency from each trophic level to the next.
