What do composers and scavengershave in common?

I'm going to assume that was 'decomposers'

Scavengers:

Eat dead animals or carrion. Break down organic material.

Decomposers:

Eat said organic material and breaks them down into chemical parts

Similarity:

Both are vital for keeping the ecosystem clean and preventing buildup of dead organisms.

Hope this helps!

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.
