All the following are limitations of ecological pyramids except
1 Not good for food web
2 Saprophytes are not given place
3 It never assumes a simple food chain
4 It does not take into account the same species belonging to two or more trophic levels.
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. Moreover, saprophytes are not given any place in ecological pyramids even though they play a vital role in the ecosystem.

The given pyramid shows the relative biomass of zooplanktons and phytoplankton in a marine ecosystem. The biomass of the zooplantktons is higher than that of the phytoplantktons because____
1 The zooplanktons have a shorter life cycle than the phytoplanktons
2 The zooplanktons have more energy
3 The phytoplanktons have extermely high turnover rate of energy
4 The phytoplanktons are individually much smaller that the zooplanktons
Explanation:
The phytoplanktons are individually much smaller that the zooplanktons

Which one of the following statements for the pyramid of energy is incorrect?
1 Its base is broad
2 It shows energy content of different trophic level organisms
3 It is inverted in shape
4 It is upright in shape
Explanation:
Pyramid of energy is upright always and cannot be inverted because when energy flows from one trophic level to another, some amount of energy is lost

Read the statements and select the best option I. Pyramid of energy can never be inverted II. A trophic level represents one species III. Saprophytes are included in the lower most bar in an energy pyramid IV. Ecological pyramids hold true only for simple food chains.
1 All are true
2 Only I is true
3 I, III and IV are true
4 I and IV are true
Explanation:
Statement I and IV are correct as the remaining two statements can be corrected as a trophic level represent the group of organisms based on the type of nutrition or food consumed, saprophytes are never a part of pyrami system.
