Ecological Pyramids & Energy Flow — NEET Biology
🔥 Predicted for NEET 2027📖 NCERT Source
In most ecosystems, all the pyramids, of number, of energy and biomass are upright, i.e., producers are more in number and biomass than the herbivores, and herbivores are more in number and biomass than the carnivores. Also energy at a lower trophic level is always more than at a higher level.
