30 POINTS!! After 70 years of absence, the gray wolf was reintroduced to Yellowstone National Park in 1995. After 1995, the elk population, which had been exploding, began to decline in numbers. Willows and aspen trees began to grow more abundantly on riverbanks. The beaver population began to increase, and songbirds were more abundant in the grasslands and riverbanks. What is the MOST LIKELY explanation for these events after the wolf was reintroduced?
A
The wolves began preying on the elk, and the beaver started using the trees to make lodges.

B
After the gray wolves came back to Yellowstone, the carrying capacity of the ecosystem increased.

C
The wolves' reintroduction altered the limiting factors for the elk, the beavers, the trees, and the songbirds.

D
The wolf's presence caused a decrease in the elk population, which allowed the riverside trees to grow more abundantly, which provided logs for the beavers' lodges and habitats for the songbirds.

The most likely explanation would be that the presence of wolves caused a decrease in the elk population, which allowed the riverside trees to grow more abundantly, which provided logs for the beavers' lodges and habitats for the songbirds.

The wolves introduced to the ecosystem must have been preying on the elk population, leading to a reduction in their population size.

Reduction in the population size of elk means that less predation on riverside trees, making them grow more abundantly.

The thriving of riverside trees provides logs for beavers' lodges and nest-building habitats for songbirds.

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.
