Which statements below accurately describe trophic levels within ecosystems? choose all that apply.
options:

only a fraction of matter consumed at lower trophic levels is transferred to higher trophic levels to produce growth and release energy through cellular respiration.

there are fewer organisms at the higher trophic levels of a food web.

50% of an organism's energy transfers to the next trophic level when it is eaten.

in a desert ecosystem, there are fewer cacti and many more coyotes.

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.
