1. Soil serves as a:

medium for plant growth,

regulator of water supplies,

recycler of raw materials,

habitat for soil organisms, and.

landscaping and engineering medium.

2. Soil organisms, which range in size from microscopic cells that digest decaying organic material to small mammals that live primarily on other soil organisms, play an important role in maintaining fertility, structure, drainage, and aeration of soil.

3. Advances in watershed, natural resource, and environmental sciences have shown that soil is the foundation of basic ecosystem function. Soil filters our water, provides essential nutrients to our forests and crops, and helps regulate the Earth's temperature as well as many of the important greenhouse gases.

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2>

\huge\boxed{Option C}

<h2>_____________________________________</h2><h2>CALORIMETER:</h2>

Calorimeter is device used for the measurement of heat. In a calorimeter we can use the temperature change of water to quantify an amount of heat.  A calorimeter just captures all the energy released (or absorbed) by a reaction in the water. So Option A and B are wrong as calorimeter don't have anything to do with providing the heat or letting the the heat in, as it is the insulated calorimeter too.

<h2>_____________________________________</h2><h2>Energy in the reaction:</h2>

In the formation of any bond there is equal amount of heat required as to break that bond. It means Energy released in the making of bond is equal to the energy required in the breaking of the bond. So Option D is wrong as it says we need more energy in making then breaking.

<h2>_____________________________________</h2><h2>Enthalpy:</h2>

Enthalpy is the total heat content of the system. As we provide energy to the reactants and the product is formed, so The enthalpy(heat content) of product is more than the Enthalpy of the reactant, Thus Option C is correct.

Enthalpy is denoted by H or Q, its formula is,

                                       H = U + PV

Where,

           U is internal energy

           PV is equals to Work done ; P = Pressure, V = Volume

Answer:

Most of the food energy that enters a trophic level is "lost" as heat when it is used by organisms to power the normal activities of life. Thus, the higher the trophic level on the pyramid, the lower the amount of available energy.
