The event described, where a layer of humus covers the sandy bottom of the lake and affects the fish populations, is an example of succession.

Succession is the process of ecological change over time in a particular area. It involves a series of predictable and sequential changes in the composition and structure of an ecosystem.

In this case, the gradual accumulation of humus, a layer of decomposed organic matter, is altering the habitat conditions in the lake.

The decline in the populations of black bass and bluegill, which build nests on the sandy bottom, can be attributed to the changing habitat.

The humus layer is likely making it difficult or impossible for these fish to construct their nests. On the other hand, fish that are capable of making nests in humus, possibly adapted to this type of substrate, are increasing in numbers.

Therefore, the observed changes in fish populations and the altered habitat due to the accumulation of humus indicate a shift in the ecological community over time, which is a characteristic of succession.

The difference between near-surface ozone and high altitude ozone is that high altitude ozone is adequate ozone as it is a UV shield and the surface zone is destructive ozone as it is harmful to life forms.

The major reasons for ozone depletion include the excessive accumulation of greenhouse gases, CFCs, propellents, manufactured chemicals, etc.

High altitude ozone is found at the topmost height in the region of the stratosphere, while surface ozone is found just above the troposphere.

Therefore, it is well described above.
