Ecological pyramids visually represent the relative energy, biomass, or numbers at different trophic levels in an ecosystem.

Ecological pyramids represent the relative number, biomass, or energy of organisms at different trophic levels in an ecosystem.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Nutrient Cycling - Carbon Phosphorus and Ecological Succession
The pyramid of numbers can be inverted, as seen in forest ecosystems where a single tree supports many consumers.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Ecological Pyramids - Number Biomass Energy
The pyramid of energy is always upright because energy is lost as heat at each trophic level, making energy transfer inefficient.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Ecological Pyramids - Number Biomass Energy
The pyramid of energy is always upright because energy is lost as heat at each trophic level according to the second law of thermodynamics.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Ecological Pyramids - Number Biomass Energy
Pyramids of biomass in aquatic ecosystems can be inverted because phytoplankton have lower biomass than the organisms feeding on them.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Ecological Pyramids - Number Biomass Energy
The pyramid of energy is always upright because energy decreases at each trophic level due to heat loss.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Ecological Pyramids - Number Biomass Energy
Primary consumers receive less energy than producers because energy is lost as heat at each trophic level.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Ecological Pyramids - Number Biomass Energy
In a forest ecosystem, the pyramid of biomass is always upright because the biomass of producers is greater than that of consumers.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Ecological Pyramids - Number Biomass Energy
Ecological pyramids represent the relative amount of energy, biomass, or number of organisms at different trophic levels in an ecosystem.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Ecological Pyramids - Number Biomass Energy
Pyramids of biomass in aquatic ecosystems can be inverted due to the rapid turnover of phytoplankton.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Ecological Pyramids - Number Biomass Energy
In a pond ecosystem, the biomass of phytoplankton (producers) is lower than that of zooplankton (consumers), creating an inverted pyramid of biomass.
