Glacier Bay in Alaska is a fjord whose lowlands were covered by glacial ice until around 230 years ago. As the glacier retreated, it left behind sediment that was exposed to plant colonization; remarkably (and fortunately for generations of ecologists), the location of the tip of the retreating glacier has been frequently documented since the late 1700s. This means that scientists have been able to develop a detailed timeline of the changes in the plant community, or _____ in Glacier Bay over time.
A. niche diversification
B. niche divergence
C. competitive exclusion
D. ecological succession
E. None of the answer options is correct.
D. ecological succession

A thorough timeline of the ecological succession or changes in the plant community that have taken place in Glacier Bay over time has been created by experts.

The Little Ice Age, a geologically recent glacial advance towards the north, is responsible for Glacier Bay as it appears now. Around 1750, the Little Ice Age's size was at its greatest. The enormous glacier that formerly filled the bay has since retreated 65 miles to its entrance mouths. In addition to being a national park, a wilderness area, a biosphere reserve, and a world heritage site, Glacier Bay serves as a homeland and a living laboratory. It's a marine park where boating into inlets, coves, and secret ports will lead to wonderful adventure. A large glacier near Juneau, Alaska, has been moving forward for more than a century and is now positioned for accelerated retreat and the birth of a new fjord.
