Which statement best describes a situation that would reduce the stability of. a forest ecosystem

Of the statements shown above the best one that describes a situation that would reduce the stability of a forest ecosystem is answer choice…

A) A fierce predator is removed from the ecosystem.

The reason is that as we already know ecosystems are very complex and diverse, with levels and relationships between organisms that keep the stability of it. Removing any level from an ecosystem may disrupt the balance that may have been established over many years.

I hope it helps, Regards. 

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.

explanation:

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.
