What you practice

These are the CBSE Class 12 Ecosystem skills this quiz is built around.

Build pyramids of number, biomass and energy for habitats.
Sequence primary and secondary succession to climax.
Trace decomposition, productivity and nutrient cycles.

A useful tip

Energy pyramids never invert because heat is lost upward, while biomass pyramids can. Asking what is measured separates the always-upright energy case from occasional inversions.
