RNA polymerase binds to the lac promoter and begins transcribing
the stretch of DNA to messenger RNA.
Therefore, in other words, the stretch of DNA is expressed. The DNA sequence of
the lac promoter 'signals' where the RNA
polymerase will bind and where transcription
will begin. Promoters are found upstream of a gene to be transcribed.

species population community ecosystem biome and biosphere. since you are asking specifically about the levels of organization in an ecosystem er leave out the levels of biome and biosphere since they are both more complex than ecosystem
the answer to this would be diffusion, where particles move from areas of high concentration to areas of low concentration!
(c) solar energy is added
