Ineed the correct answer, don't guess worth 50 in many ecosystems a shortage of limits the growth of many producers a. oxygen b. water c. bacteria

Producers are organisms, such as plants, that produce their own food, and are then eaten by other organisms.  Water shortages (droughts) limit the growth of many producers.  Without sufficient water, plants cannot undergo photosynthesis.  This limits their growth, and limits the available energy sources for the entire ecosystem.  

Nutrients  are water soluble and they are easy to drained away, so they are no longer available in plants.Many ecosystems limits the growth of many producers nitrogen as the most common limiting nutrient.  (trust me this isn't copied)

So what it will be is.

In many ecosystems a shortage of water limits the growth of many producers.

Hope this helped

If you have any questions reply and ill comment asap.

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.

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]
