Question

The graphic presentation of various aspects of ecosystems are in the form of pyramids. When such a presentation is made with reference to energy at different trophic levels, it will make

• A. An erect pyramid
• B. An inverted pyramid
• C. A cylinder
• D. A pyramid of variable shape

Answer 1

The correct option is A An erect pyramid

The pyramidal representation of trophic levels of different organisms based on their ecological position [producer to final consumer] is called as an ecological pyramid. The food producer forms the base of the pyramid and the top carnivore forms the tip. An energy pyramid represents the amount of energy at each trophic level and loss of energy at each transfer to another trophic level. Hence the pyramid is always upward, with a large energy base at the bottom.

So the correct option is 'an erect pyramid'.
