Question

An imaginary pyramid of numbers is given. Which one of these combination of organisms can be placed in this pyramid?

• A. Level PP is peepal tree and level SC is sheep
• B. Level PC is hawk and level SC is cats
• C. Level PP is phytoplankton in sea and topmost level TC is whale
• D. Level PC is insects and level SC is small insectivorous birds

Answer 1

The correct option is D Level PC is insects and level SC is small insectivorous birds

The fourth option is the correct answer, as it represents insects as the primary consumers, which form the trophic level with highest number of organisms. They are mostly dependent on one primary producer, like a tree (as represented in the image), and secondary consumers are insectivorous birds, which are comparatively lesser in number than the insects which form the previous trophic level.
