four students drew different illustrations to show the flow of energy in a field ecosystem. Which of the illustrations below is most accurate?

The correct answer is the second illustration

Explanation:

Energy flows from one level or organism to another as one organism takes nutrients from another. In this context, the first level is plants including oats and these take nutrients from the sun and the soil to obtain energy. On the second level are herbivores including mice that feed on plants. These can be followed by other organisms such as carnivores, for example, foxes and even top predators. Finally, the last level is decomposers these include bacteria and other organisms that can obtain nutrients from plants and animals as they die and decompose.

According to this, the correct diagram is the second one because these shows accurately how energy flow from the sun to plants oats), then to animals (mouse), and finally the energy of plants and animals flows to the decomposers.
