The pyramid of biomass in marine ecosystem is generally inverted because
1 Primary productivity of marine ecosystems is lesser than that of terrestrial ecosystems
2 The size of individual organisms decreases from lower trophic levels to higher trophic levels
3 Compared to primary consumers, phytoplankton synthesize less biomass per unit time per unit area
4 The standing crop of phytoplankton at any given moment is lower than that of primary consumers
Explanation:
Phytoplankton have shorter lifespan and they multiply much faster. Zooplankton have longer lifespan. A single generation of zooplankton consume several generations of phytoplankton. Hence at any given moment, the standing crop of zooplankton is higher than that of phytoplankton (Standing crop is the mass of biomass at a particular time in a trophic level).

Given below is an imaginary pyramid of numbers. What could be one of the possibilities about certain organisms at some of the different levels?
1 Level PC is "insects" and level SC is "small insectivores birds".
2 Level PP is "phytoplanktons" in sea and "whale" on top level TC
3 Level PP is "pipal trees" and the level is "sheep"
4 Level PC is "rats" and level SC is "cats".
Explanation:
Option 1 is correct.

Which of the following statement is correct?
1 Pyramid of number in grassland ecosystem is upright.
2 Pyramid of number in aquatic ecosystem is inverted.
3 Pyramid of biomass in tree ecosystem is inverted.
4 Pyramid of biomass in aquatic ecosystem is upright
Explanation:
In a grassland ecosystem, number of plants or grasses or herbs will support fewer number of grasshoppers that will support still lesser number of frogs, still lesser number of snakes etc. Hence pyramid of number in a grassland ecosystem is upright.
