A diagram showing four rectangles stacked in a pyramid shape. From bottom to top, each rectangle gets smaller and shows energy values in kilocalories per meter squared per year. The producer level at the bottom has a value of twenty thousand eight hundred and ten. Above this the primary consumer level has a value of three thousand three hundred and sixty eight. Above this, the secondary consumer level has a value of three hundred and eighty three. At the top is the tertiary consumer level with a value of twenty one.
