Answer 1

It’s the second option

In the tree,there r many insects,parasites or birds feeding on it

Thus unlike any normal ecosystem where the organisms decrease at each tropic level,here,there is only one producer and many herbivores. Hence the pyramid is narrow at the bottom level or producer level and broad as the trophic level increases making an upright pyramid.

The answer is C
