Answer:
The simplest definition of an ecosystem is that it is a community or group of living organisms that live in and interact with each other in a specific environment.
That would be a plant. Like a tree, Flower, Hedge, etc. That is because of Photosynthesis. Photosynthesis is a chemical reaction that makes compounds (glucose) by capturing light from its leaves, and water from its roots.

Answer:
True
Explanation:
Gene expression, which involves the transcription of DNA into mRNA and the subsequent translation of mRNA into proteins, is regulated in the cell of prokaryotes i.e. it is kept under control. This regulatory process, however, is done at the TRANSCRIPTIONAL LEVEL, in prokaryotic organisms like bacteria.
DNA binding proteins called transcription factors bind to the promoter region of a gene and either facilitates/enhance the binding of RNA polymerase or inhibits its binding. The enhancers are called ACTIVATORS while the inhibitors are called REPRESSORS.
