The correct answer is option D, None of the choice.
Prokaryotes like Escherichia coli are used in drug production. Rhizobium bacteria (prokaryotes) in the soil, form symbiotic relationship with the roots of the plant to fix nitrogen. And prokaryotes are measured in terms of colony-forming units (CFU) of bacteria to produce nutritious yoghurt.
is the answer below correct? because i know the option "to synthesize drugs" is wrong.
The correct answer would be C - to form a symbiotic relationship and obtain ammonia.
from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.
it's anything that aren't producers and consumers.
you've got to be clear on what "this" is
a. to synthesize drugs
