In a beach ecosystem what can limit growth of organisms ?

The correct answer is ocean and rocks.

Explanation:

In a beach ecosystem, the rocks and oceans may restrict the growth of organisms. This is due to the activity of ocean tides that may result in the organisms inhabiting the rocks and other regions to flow away. The ocean and rocks in combination may result in the formation of conditions in which various organisms cannot develop. Due to ocean currents, the rocks may sometimes move away, this signifies that the organisms living in the rocks may move away to another place where their survival may become impossible.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

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.
