The answer is: A decrease in the number of Trees
Woodpeckers are known for their use of finding food sources on the trucks of trees. They are also popularly own for beating their beaks against a tree trunk in order to provide vibrations and communicate with other woodpeckers.
Contrary to popular belief, they do not eat wood, but trees as a whole form an important part of their habitat.
Hence, the deforestation, cutting down of trees and urbanization can all lead to the decreasing number of woodpeckers in the ecosystem.
Since the early 20th Century two species of American woodpeckers are already considered extinct.
Answer:
Polymerase chain reaction (PCR)
Explanation:
Polymerase chain reaction (PCR) is a method by which a target DNA fragment is amplified to produce millions of copies. In PCR, the Taq polymerase enzyme uses nucleotides and primers to replicate a small DNA segment <em>in vitro</em> and produces two DNA molecules. The newly formed DNA molecules are denatured by heating to facilitate their replication to produce four double-stranded DNA molecules. In this way, the number of DNA molecules is doubled in each cycle. Therefore, the small amount of DNA obtained from the minuscule spot of blood on a murder suspect’s shirt can be amplified using PCR.

The appropriate response is carbon dioxide. Since carbon dioxide responds with water to shape carbonic corrosive, an expansion in CO2 brings about an abatement in blood pH, bringing about hemoglobin proteins discharging their heap of oxygen.
An excess of carbon dioxide in your blood can hurt your body's organs. Both of these issues—a low oxygen level and a high carbon dioxide level in the blood—can happen in the meantime. Maladies and conditions that influence your breathing can cause respiratory disappointment.
