The correct match among the following is
-
Producers--- act upon the decomposed substances and transform them into different forms of inorganic and organic substances
-
Consumers--- are autotrophic members of ecosystem
-
Decomposers--- feed upon dead decaying living organisms and break them into simpler compounds fit for use of producers
-
None of the above
The green plant in the ecosystem-terminology are called as producers. All animals depend on plants (directly or indirectly) for their food needs. They are hence, called as consumers and also heterotrophs.
