Mr. $X$ is eating curd/yogurt, for this food intake in a food chain he should be considered as occupying:
1 First trophic level
2 Second trophic level
3 Third trophic level
4 Fourth trophic level
Explanation:
Mr. X eating curd/yogurt should be considered as occupying third trophic level. Producers or green plants (first trophic level) are consumed by herbivores (second trophic level). And from them curd, yoghurt (made from dairy breed) is consumed by third trophic level likes man.

The pyramid of energy is always upright for any ecosystem. This situation indicates the fact that........
1 Carnivores have a better energy conversion efficiency than herbivores.
2 Producers have the lowest energy conversion efficiency.
3 Herbivores have a better energy conversion efficiency than carnivores.
4 Energy conversion efficiency is the same in all trophic levels.
Explanation:
Herbivore have a better energy conversion efficiency than carnivores because energyconversion efficiency becomes decreases in higher trophic level. Pyramid of energy is always upright.

Net primary productivity (NPP) in an ecosystem is
1 $\mathrm{GPP}-\mathrm{R}=\mathrm{NPP}$
2 $\mathrm{GPP}+\mathrm{R}=\mathrm{NPP}$
3 $\mathrm{GPP}-\mathrm{NPP}=\mathrm{R}$
4 $\mathrm{R}-\mathrm{NPP}=$ GPP
Explanation:
Net primary productivity (NPP) in an ecosystem is GPP- $\mathrm{R}=$ NPP. Net primary productivity or NPP can be defined as the rate of accumulation $f$ biomass or energy. the energy utilized during metabolic processes such as respiration is excluded from gross productivity (GPP). NPP is calculated primarily by an increase in the biomass in unit time per unit area.

Which of the following pyramids is always upright and can never be inverted?
1 Pyramid of biomass
2 Pyramid of number
3 Pyramid of energy
4 Both (a) and (c)
Explanation:
Pyramid of energy is always up right because when energy flow from particular trophic level to next tropic level, some energy is always lost as heat at each step, so the energy in subsequent trophic level is always less than the energy in the previous level. Hence pyramid of energy is always upright and can never be inverted. - The pyramid of biomass is never upright. - The pyramid of number is always upright.
