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.

Answer: Option D
Explanation:
None of the characters are true regarding bacteria and archaea. Both of the species have different composition of cell wall. The cell wall of bacteria is made of peptidocglycan and archaea's cell wall lack peptidoglycan.
Bacteria and archaea both are very diverse and are found in variety of environment. They both are found in the extreme environmental conditions.
Archaea and bacteria both are not derived from the eukarya. According to the endosymbiotic relationship the eukaryotes are developed from the prokaryotes.
hence, none of the statements are true.
