Answer:

Through the process of Anthropogenic additions of N and P to the fresh water system can provide a strongest evidence for the above mentioned hypothesis.

Explanation:

As phosphorus is less mobile than nitrogen compounds, it is less likely to be found in fresh water where the organisms fail to access it. Phosphorus bounds mostly in the terrestrial ecosystem and in the aquatic matters because it has a sticky compound.

Thus it is a limited nutrient in freshwater lake like Mairead. However, this hypothesis can be different depending on other factors. Like, by adding anthropogenic N and P, this balance can be affected largely.

6. Applying Ideas: Suppose someone dumped left over motor oil on a driveway. Could this disposal
Rufina [12.5K]

Answer:

If they are looking for one BEST answer, it is the water.

If looking for top two, it is water and soil.

Realistically, however, this disposal can contaminate all 3.

Let me explain:

The motor oil that is dumped on a driveway first makes its way into the soil. The freshwater found in this soil becomes contaminated with motor oil and can eventually runoff into the ocean. Once this liquid evaporates, it then becomes air pollution. Shortest, best answer tho is water.

Hope this helps. Have a great day!

Verizon [17]

because the total time for restoration is lengthy, peat can be considered a fossil fuel. The correct option is B.

<h3>What exactly are fossil fuels?</h3>

Fossil fuels are fuels derived from the remains of dead plants and animals that decomposed over time under intense heat and pressure.

Because their replenishment time is longer than a human lifetime, fossil fuels are non-renewable energy sources.

Some examples of fossil fuels are petroleum, coal, etc.

The missing options of the question are:

  1. peat is a fossil fuel because rewetting it takes only 3-5 years.
  2. peat is a fossil fuel because the total time for restoration is lengthy.
  3. peat is not a fossil fuel because it has biologic origins, making it a biofuel.
  4. peat is not a fossil fuel because humans can promote the replenishment of peat.

The restoration process of peat takes a long time of more than 100 years. As a result, because the total time for restoration is lengthy, peat can be considered a fossil fuel.

Thus, the correct option is B.
