Answer:

D. mixture

Explanation:

because the mixture is not part of an atom

As per the given scenario, the sample can be any of the following, except element. The correct option is C.

A substance that is unable to broken down chemically into smaller molecules.

An element is made up of atoms with the same atomic number, which means that each atom possesses the same count of protons in its nucleus as the other atoms in the element.

A chemical compound is a chemical substance made up of many identical molecules made up of atoms from multiple elements that are held together by chemical bonds.

A molecule made up of only one element's atoms is thus not a compound.

A scientist discovers three types of atoms in a sample of matter. Except for elements, the sample can be any of the compound, molecule or mixture.

Thus, the correct option is C.

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.
