Add Integrated content about the Lindeman Spine graph

[Yu-Haolin]

Very useful work and this work makes it freer to explore the ecosystems. Some scientists also focus on the energy flow throughout the ecosystem among different trophic levels. If it is possible, I hope the author could add integrated content containing the indexes of different trophic levels (predation, flow to the detritus, respiration, exports and catches, TST%, consumption, and flow from detritus) about the Lindeman Spine.
