Limitation of ecological pyramids is/are :-
1 It does not take into account the same species belonging to two or more trophic levels
2 It assumes a simple food chains, it does not accommodate a food web
3 Saprophytes are not given any place in ecological pyramids
4 All of them
Explanation:
There are certain limitations of ecological pyramids such as it does not take into account the same species belonging to two or more trophic levels. It assumes a simple food chain, something that almost never exists in nature, it does not accommodate a food web. Saprophytes are not given any place in ecological pyramid even though they play a vital role in the ecosystem.

Which of the following statements regarding ecological pyramid is true?
1 Ecological pyramids demonstrate a loss in energy at each step of the trophic level
2 Ecological pyramids show that carnivore are more than herbivores.
3 Ecological pyramid depict the total biomass of an ecosystem minus total energy used in respiration
4 More than one option is correct.
Explanation:
Transfer of energy from one trophic level to another trophic level follows the 10 percent law which says that \(10 \%\) of energy is transferred to each trophic level from the lower trophic level.

Statement A : Pyramid of energy may be upright or inverted. Statement B : Only \(20 \%\) of energy goes to next trophic level.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Both statements are incorrect. Pyramid of energy is always upright and \(10 \%\) of energy is transfered.

In a pyramid, carnivores cannot occupy
1 3 trophic level
2 3 and 4 trophic levels
3 1,2 trophic levels
4 4 and 5 trophic levels
Explanation:
In a pyramid, carnivores cannot occupy 1,2 trophic levels as these are occupied by producers and herbivores.
