Explanation
The correct answer is (c) Upright.
The pyramid of energy is a graphical representation of the flow of energy through the trophic levels of an ecosystem. It represents the amount of energy available at each trophic level and the transfer of energy from one level to another.
The pyramid of energy is typically upright, meaning that the energy decreases as you move up the trophic levels. This is because energy is lost as heat during metabolic processes and is not fully transferred from one level to the next. As a result, the energy available to higher trophic levels is reduced compared to the lower levels.
Options (a) Inverted and (b) Spindle-shaped are not correct because the pyramid of energy is generally not inverted or spindle-shaped. In an inverted pyramid, the energy would increase as you move up the trophic levels, which is not the case in most ecosystems.
Therefore, the pyramid of energy is usually upright (option c) in the majority of ecosystems.
