Tiger affects the size and distribution of the plant population in its community.

Option B

Explanation:

We are aware of the facts of nature where the law of nature has created a proper food pyramid. In the food pyramid the tiger stand first as the predator. The predator is very important to keep the food chain in proper balance.

If the Tiger species is gone then there is no predator to devour the herbivorous animals then there will be a rapid increase in the herbivorous population. This herbivores if multiplied more eat up all the plants that are available. Hence no vegetation then no rain and the whole ecosystem become imbalanced. So the presence of this predator alone can keep the ecosystem alive .

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.
