(B) Upright pyramid
(C) Spindle shape pyramid
(D) None of the above
​
answer immediately

Answer 1

energy pyramid always upright except in Detritus Food Chain

Answer 2

Answer: The correct answer is inverted pyramid

Explanation: The food chain is considered as the system where the energy is transferred from one level to another level in a hierarchical system and the pyramid of numbers is the pyramid that represents the total number of individuals in a population at a different trophic level. So according to the number, the pyramid of numbers may not upright or inverted. In an upright or erect pyramid of numbers, the number of individuals is decreased from lower level to higher trophic level. It is seen in the grassland ecosystems. The ecological food chain of grass (producer) - grasshopper/deer (herbivores) - rodent/tiger (primary carnivores) - snake (secondary carnivores) is an example of the erect pyramid of numbers. An insect (primary consumer) - chicken (secondary consumer) - human (tertiary consumer) is another example of the erect pyramid of numbers. In an inverted pyramid of numbers, the number of individuals increases from lower level to higher trophic level. It is seen in the tree ecosystem. The ecological food chain of trees (producers)- birds (herbivores) - parasites is an example of an inverted pyramid of numbers.
