Which one of the following statements for pyramid of energy is incorrect, whereas the remaining three are correct?

It is upright in shape
Its base is broad
It shows energy content of different trophic level organisms
It is inverted in shape

The correct answer is D. It is inverted in shape.

A pyramid of energy is a graphical representation of the energy flow through an ecosystem. It is typically drawn as a triangle, with the producers at the base and the top consumers at the apex. The width of each level represents the amount of energy at that level, and the height of each level represents the number of organisms at that level.

The pyramid of energy is always upright in shape, because there is always a loss of energy as it moves up the food chain. This is because some of the energy is used by the organisms at each level for their own metabolism, and some of it is lost as heat.

The pyramid of energy is a useful tool for understanding the flow of energy through an ecosystem. It can be used to calculate the productivity of an ecosystem, and to identify the limiting factors on productivity.

Here is a more detailed explanation of each option:

  • Option A is correct. The pyramid of energy is always upright in shape.
  • Option B is correct. The base of the pyramid is broad because it represents the producers, which are the most abundant organisms in an ecosystem.
  • Option C is correct. The pyramid of energy shows energy content of different trophic level organisms. The amount of energy at each level decreases as you move up the food chain.
  • Option D is incorrect. The pyramid of energy is always upright in shape, and it is never inverted.
