Given below is an imaginary pyramid of numbers. What could be one of the possibilities about certain organisms at some of the different levels?
Options
- ALevel PC is insects and level SC is small insectivorous birds
- BLevel PP is phytoplanktons in sea and Whale on top level TC
- CLevel one PP is pipal trees and the level SC is sheep
- DLevel PC is rats and level SC is cats
Correct answer
A. Level PC is insects and level SC is small insectivorous birds
Step-by-step solution
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, P C 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.
