(C) In a tree ecosystem,the pyramid of numbers is spindle-shaped (partly inverted and partly erect).$1$. The base represents a single large tree (producer),which is small in number.$2$. The next trophic level consists of many herbivorous birds or insects feeding on the tree,which are larger in number.$3$. The top trophic level consists of a few predatory birds or parasites,which are smaller in number again.Thus,the pyramid is narrow at the base,broad in the middle,and narrow at the top,making it partly inverted and partly erect.

The pyramid of numbers becomes partly inverted and partly erect for which of the following?
