Which type of ecological pyramid best traces the flow of matter through an ecosystem?good

In ecology, a food chain can be presented in a pyramid
chart. To trace the flow of matter through the ecosystem, one could consider a pyramid
of  numbers. At the base, which is the widest part of the pyramid, the most organisms in
the food chain would be present and would contain the most matter. That level would
contain the producers or autotrophs. This level would contain the most organisms in
terms of sheer number and thus, the most matter(as well as energy). The level above
this, the consumers, specifically herbivores, would have less matter as their numbers
would be far less. And, it takes a lot of plant matter, to keep one herbivore alive. So,
as you go from the bottom level up to the next level, the number of organisms, continues
to go down.  The amount of matter will decrease with each level you go up to. The third
level in the pyramid would be consumers(carnivores) which would eat the herbivores in
the previous level. Again, the amount of carnivores, compared to the herbivores in the
level below them, decreases. It would take a lot of herbivores, which are prey to feed
one large carnivore. So, as the pyramid continues to the top, the number of organisms in
each level decreases, and so does the amount of matter (as well as energy) in that
level.
