This is false. Organisms may play several important roles in an ecosystem. Consider for example and ocean shore environment occupied by a particular species of crab. The crabs are scavengers and eat any organic matter they encounter. They therefore play an important role in the cycling of nutrients in the ecosystem. The crabs are however also an important source of food for a range of other species occupying the same habitat, including octopi, certain fishes and sea otters. Therefore, the crabs are an important part of the food web in the ecosystem. Many species similarly occupy multiple important roles in an ecosystem.
DNA is the molecule, which is the source of information for transcription.
• During the process of transcription, RNA polymerase is an enzyme, which is accountable for copying a sequence of DNA into a sequence of RNA.
• The RNA polymerase monitors the phenomenon of transcription.
• At the time of transcription, the information is stored within a molecule of DNA, which is further copied into a new molecule of messenger RNA.
Thus, the correct answer is DNA.
