Sulfur dioxide and nitric oxide (NO) are the primary air pollutants, and ozone is a secondary pollutant (though there are negligible direct emissions of the gas itself). Nitrogen dioxide (NO2) is both a primary and secondary air pollutant. Other important gaseous pollutants are: ammonia, carbon monoxide, volatile organic compounds (VOCs) and persistent organic pollutants (POPs) which we discuss below.
Living organisms have an internal hierarchy within an ecosystem. They are the primary producers, consumers and decomposers. Producer. Primary producers are photoautotrophs. Primary producers include all green plants, algae and cyanobacteria.Photoautotrophs use light as the source of energy and inorganic carbon as the source of carbon.onsumers are of different types. Primary consumers feed directly on primary producers and they are called herbivores. Secondary consumers feed on primary consumers and tertiary feed on secondary etc.
