Prokaryotes that break down dead organisms in an ecosystem are called

The correct answer is -

Decomposers.

Prokaryotes are those organisms that are devoid of nucleus and membrane bound subcellular compartments (called cell organelles).

They primarily include bacteria, which act as decomposers, by breaking the organic compounds of different life forms such as plants and animals into simpler forms (which are vital nutrients such as carbon, nitrogen, phosphorous) that are returned back to the environment.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
