[A]The genetic resources of the earth.
[B]Exclusive Economic Zones (EEZs)
[C]Marine and coastal areas significant for ‘eco-tourism’.

18.

In which of the following ecosystems, the pyramid of biomass is ‘inverted’ in shape?
[A]Pond ecosystem
[B]Grassland ecosystem
[C]Forest ecosystem
[D]None of the above

Pond ecosystem
Biomass is the amount of living material in an organism. The pyramids of biomass represent the relationship between different trophic levels in terms of biomass. In grassland and forest ecosystems, there is generally a gradual decrease in biomass of organisms at successive trophic levels from the producers to the consumers. Their pyramid of biomass is upright. In aquatic ecosystem the producers are small organisms with least biomass and the biomass gradually increase towards the apex of the pyramid. Thus the pyramid of biomass of aquatic ecosystems is inverted in shape.

19.

What is the direction of flow of energy in an ecosystem?
[A]Unidirectional
[B]Bidirectional
[C]Multidirectional
[D]Cyclic

Unidirectional
The energy enters the plants from the sun through the photosynthesis process. This energy is then passed on from one organism to another in a food chain. The flow of energy in the ecosystem is unidirectional because the energy lost as heat from the living organisms of a food chain cannot be reused by plants in photosynthesis. During the transfer of energy through successive trophic levels in an ecosystem, there is a loss of energy all along the path.

20.

Which of the following is considered as the secondary pollutant?
[A]Ozone
[B]Benzene
[C]Sulphur dioxide
[D]Carbon monoxide

Ozone
Primary pollutants are directly emitted from the sources. Examples of primary pollutants are carbon monoxide, carbon dioxide, sulphur dioxide and benzene etc. Secondary pollutants are not emitted directly. They are formed from the combination of primary pollutants with some other compound. Examples of secondary pollutants are Ozone, Formaldehyde, PAN (peroxy acetyl nitrate) and Smog etc.
