Describe a food chain for a temperate forest community that contains at least four links. use the following organisms: grizzly bears, oak trees, mice, squirrels, deer, robins, foxes, mushrooms, grass plants, and grasshoppers. identify the level of each organism in the food chain.

Oak trees, grass plants are Producers.

Grasshoppers, deer, mice, and squirrels are Primary consumers, they are eating producers.

Foxes, robins are Secondary consumers, they are eating primary consumers(depending on their nature)

Grizzly bears are Tertiary consumers, they are eating secondary consumers (like snakes)

Mushrooms are decomposer (which decompose, organic material such as remains of dead material)  

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.
