Hello,
Here is your answer:
The proper answer to this question is option C "<span>biotic".
Here is how:
Salt is consider a biotic factor because of it concentration which makes it a factor of the ecosystem.
Your answer is C.

The experimental procedure to test whether plants that are exposed to music grow faster than those that are not should follow the following steps. First, the plants must all be placed in a place where all must be exposed in the same type of environment in terms of sunlight, temperature, water and soil. Second, one of the plant must be exposed to two to three hours of classical music per day. Then you should expose one plant to five to six hours of music per day too. The remaining two plants will be treated as your control plants wherein these will be not exposed to music at all. Before you begin the experiment, you should take pictures of each plant. Next, you should take pictures after two, four and eight weeks. After the steps, observe any visible and palpable differences between the plants which were exposed to music and those that have note. Lastly, also observe the differences between the plants which were exposed to less and those exposed to more music.

An ecological pyramid (also trophic pyramid, Eltonian pyramid, energy pyramid, or sometimes food pyramid) is a graphical representation designed to show the biomass or bioproductivity at each trophic level in a given ecosystem.
A pyramid of energy represents how much energy, initially from the sun, is retained or stored in the form of new biomass at each trophic level in an ecosystem. Typically, about 10% of the energy is transferred from one trophic level to the next, thus preventing a large number of trophic levels. Energy pyramids are necessarily upright in healthy ecosystems, that is, there must always be more energy available at a given level of the pyramid to support the energy and biomass requirement of the next trophic level.
A pyramid of energy shows how much energy is retained in the form of new biomass at each trophic level, while a pyramid of biomass shows how much biomass (the amount of living or organic matter present in an organism) is present in the organisms. There is also a pyramid of numbers representing the number of individual organisms at each trophic level. Pyramids of energy are normally upright, but other pyramids can be inverted or take other shapes.
Ecological pyramids begin with producers on the bottom (such as plants) and proceed through the various trophic levels (such as herbivores that eat plants, then carnivores that eat flesh, then omnivores that eat both plants and flesh, and so on). The highest level is the top of the food chain.
Answer: Mutation. The allelic variations that make evolution possible are generated by the process of mutation, but new mutations change gene frequencies very slowly, because mutation rates are low. Assume that the gene allele A1 mutates to allele A2 at a rate m per generation and that at a given time the frequency of A1 is p.
