Answer:

Decayed organisms are compressed underground

Explanation:

Fossils are the remains of organisms that are buried in a rock during sediment deposition over long geological time period. Since the bodies of these organisms is made of organic compounds, the high pressure of the overlying rock turns them into the hydrocarbons or fossil fuels. Therefore, option D is correct.

On the other hand, options A-C are incorrect because of following reasons:

Burning of natural gas doesn't form fossil fuel but CO2. In fact, natural gas is also a form of fossil fuel which is released from a rock hosting fossils.
Sunlight doesn't convert grass to coal. In fact, sunlight cannot penetrate deeper into the geological rocks. Rather it will cause the weathering of surface sediments directly exposed to sunlight.
Farms are not used to produce natural gas rather natural gas is produced inside a rock hosting bodies of living organisms.

3. What happens to the energy that is consumed by any level in an energy pyramid?

beks73 [17]

Answer:

The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.

Carbon dioxide (CO2) combines with a five-carbon compoundIn one to three sentences, describe what happens during the reduction s

alexandr1967 [171]

We are well aware that there are two stages of photosynthesis:

Light dependent reactions
Light independent reactions/ Calvin cycle/ dark reactions.

Calvin cycle or light-independent reactions:

This comprise the process during which carbon dioxide enters into the leaves of plants and passes through series of steps to form sugar or food. This process depends on the supply of ATP, (the ATP that is formed previously during light dependent reactions).

Now there are three stages of Calvin cycle:

1) carbon fixation
2) reduction
3) regeneration

During the process of carbon fixation CO2 combines with a 5-carbon compound called RuBP or ribulose-1,5-bisphosphate which results in the synthesis of a 6-carbon compound that splits up in to 2 three carbon compounds called phosphoglyceric acid (3-PGA).

Here out focus will be the process of Reduction.

Reduction is the second stage of Calvin cycle during which phosphoglyceric acid (3-PGA) is converted to glyceraldehyde-3-phosphate (G3P) that is a sugar. During the process of reduction, energy in the form of ATP and NADPH are used for the conversion of 3-PGA to G3P. As 3-PGA is reduced to G3P, therefore this process is known as reduction.

After reduction, a series of reactions occur that lead to the synthesis of glucose but since focus of our question was reduction, so you can see more details of the process in attached figure.

Hope it helps!
