When the number of organisms at successive levels are plotted, they assume the shape of a pyramid. This is called the pyramid of: [NCERT - NC-II- 213]
1 Energy
2 Number
3 Biomass
4 Both 1 and 3
Explanation:
b The base of each pyramid represents the producers or the first trophic level while the apex represents tertiary or top level consumer. The three types of ecological pyramids that are usually studied are (a) pyramid of number; (b) pyramid of biomass and (c) pyramid of energy.

In an ecosystem, the population of : [NCERT - NC-II- 210]
1 Primary producers are more than that of primary consumers
2 Secondary consumers are largest becaue they are porwerful
3 Primary consumers more than parimary producers
4 Primary consumers are least dependent upon primary producers
Explanation:
a In most ecosystems, all the pyramids, of number, of energy and biomass are upright, i.e., producers are more in number and biomass than the herbivores, and herbivores are more in number and biomass than the carnivores. Also energy at a lower trophic level is always more than at a higher level.

If we completely remove the decomposers from an ecosystem, its functioning will be adversely affected, because : [NCERT - NCERT-II-210]
1 Mineral movement will be blocked
2 The rate of decomposition will be very high
3 Energy flow will be blocked
4 Herbivores will not receive solar energy
Explanation:
a By the decomposition complex organic matter break into simpler inorganic substance like carbondioxide, water and nutrients. Nutrients are again involved in mineral cycling. Hence in absence of decomposer this process disturbed.

Basic requirement for any ecosystem : [NCERT - NCERT-II-209]
1 Decomposition
2 A constant input of solar energy
3 Nutrient cycling
4 Trees
Explanation:
b A constant input of solar energy is the basic requirement for any ecosystem to function & sustain .
