All of the following are TRUE statements about prokaryotes EXCEPT: A - Some prokaryotes can live in extreme habitats.

B - Prokaryotes are the most important photosynthesizers.

C - Some prokaryotes are important as decomposers.

D - Prokaryotes dominate the biosphere

E - Prokaryotes are the most numerous organisms on earth

B - Prokaryotes are the most important photosynthesizers.

Explanation:  

There are some phototrophic prokaryotic organisms such as cyanobacteria and photosynthetic bacteria that carry out photosynthesis through chlorophyll-like pigments (bacteriochlorophylls) that enable them to absorb light and by using water as an electron donor in a similar way to plants. These organisms contain specialized plasma membranes which contain these photosynthetic pigments. Nonetheless, it is important to highlight that algae are the most important photosynthetic organisms in aquatic environments, while plants are the most important photosynthesizers in terrestrial environments.

O The final product of cellular respiration is electromagnetic radiation.

The energy conversion in cellular respiration takes place in the chloroplast.

The main source of chemical energy in cellular respiration is water.
