Which one of the following statements for pyramid of energy is incorrect?

Pyramid of energy shows the amount of energy at each trophic level. 

• Producers are the green plants that make their own food through the process of photosynthesis with the help of carbon dioxide, water, and sunlight. They are large in number and have a broad base.
• The energy flows from a particular trophic level to the next trophic level.
• In this transfer of energy, some amount of energy is always lost as heat at each trophic level. Each bar in the energy pyramid shows the amount of energy present at each trophic level in a given time.
• Amount of energy at each trophic level is as follows: $primary producer>primary consumer>secondary consumer>tertiary consumer$
• Hence, the pyramid of energy is always upright and never inverted.
