Question

Answer question no.33.
Give some explanation. :))

Answer 1

it is because actually the pyramid is
producers>consumers>secondary consumers>tertiary consumers>decomposers
consumers are herbivores
if these herbivores are disappeared then there will be no pyramid
if there are no herbivores then no one will eat producers
producers are plants..

Answer 2

herbivores eat producers and herbivores are eaten by secondary consumers. If herbivores are not their then secondary consumers won't get food and they will die.so there are only producers left
