Which of the following ecological pyramid are always inverted?
1 Pyramid of number of insects feeding on a big tree and pyramid of biomass in pond ecosystem
2 Pyramid of number in pond ecosystem and pyramid of biomass in pond ecosystem
3 Pyramid of number in grassland and pyramid of mass of insects feeding on a big tree
4 All of the above
Explanation:
The pyramid of biomass of lake or pond ecosystem is always inverted, where a large fish eat large number of small zooplanktons and pyramid of number of insects feeding on a large tree is also inverted as single tree or a small leaf can support large number of parasites.

Biomass of each succeeding trophic level is
1 More than preceding one
2 Constantly fixed
3 Less than preceding
4 Equal to next trophic level
Explanation:
Amount of living or organic matter present in an organism is called biomass. There is a progressive reduction in biomass in pyramid of biomass, because \(10-20 \%\) of biomass is transferred from lower trophic level to higher trophic level, the remaining is consumed to provide energy for giving heat

Ecological pyramids doesn't accommodate
1 Food chain
2 Biomass
3 Energy
4 Decomposer
Explanation:
Decomposers do not occupy any place in trophic level in the food pyramid.
