Explanation

The given figure shows spindle - shaped pyramid of number in single tree ecosystem. Here, a single large sized tree provides food to a large number of herbivores which support a few carnivores and the later are eaten by small number of top carnivores. So here PP is used for producer, i.e. single tree PC is Primary Consumers, i.e. large number of insects , SC is Secondary Consumers, i.e. small insectivorous birds and TC is Top consumers, which may be eagles or falcon etc.
