A: Ecological pyramid of biomass is generallly inverted in sea R: Biomass of fishes for exceeds that of phytoplanktons.

Draw the pyramids of biomass in sea and in a forest. Explain giving reasons why are the two pyramids different ?

In an open ocean, the biomass of primary producers (microscopic algae) is often lower than the biomass of higher trophic levels (zooplanktons and fish), as illustrated below by an inverted pyramid of biomass. How can there be enough food in an open ocean to support the higher trophic levels?

Study the following ecological pyramids carefully. Mathc the following statements I,ii and iii with gien pyramidsa, B and C and select the correct answer. (i) Inverted pyramid of biomass depicting small standing crop of phytoplanktons supporintg a large standing crop of zooplanktons (ii) Pyramid of numbers in a grassland ecosytems showing about 6 milion producers. (iii) Upright pyramid of biomass

It is often said that the pyramid of energy is always upright. On the other hand, the pyramid of biomass can be both upright and inverted." Explain with the help of example and sketches .

Study the following statements and select the incorrect ones. (i) Pyramids of energy and yearly biomass production can never be inverted, since this would violate the laws of thermodynamics. (ii) Pyramids of standing crop and numbers can be inverted, since the number of organisms at a time does not indicate the amount of energy flowing through the system. (iii) There are certain limitations of ecological pyramids such as they do not take into account the same species belonging to two or more trophic levels. (iv) Saprohytes are not given any place in ecological pyramids even though they play a vital role in the ecosystem.

Construct a pyramid of biomass starting with phytoplankton. Label trophic levels. Is the pyramid upright or inverted? Why?

Consider the following statements and select the correct option stating which ones are true (T) and which ones are false (F). (i) Pyramid of biomass is upright in the forest ecosystem and inverted in the grassland ecosystem. (ii) Pyramid of numbers is inverted in grassland and upright in aquatic ecosystem. (iii)Pyramid of energy depicts the rate of energy flow or productivity at successive trophic levels . (iv) Ecological pyramids have no place for detritivores and decomposers though they play an important role in an ecosystem.
