Why would competition be considered a limiting factor within an ecosystem

Competition could be considered a limiting factor within an ecosystem because as the populations grow, they will compete for shelter and available resources. Also, as populations become denser, the risk of disease increases.   The competition can be considered as a limiting factor within an ecosystem because there is a limited supply of resources that can be used and consumed.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
