B. What happens to the materials that make up a living organism after it dies.

Explanation:

An ecosystem can be defined as the natural living habitats of both living and non-living organisms.

Ecosystem services such as plant pollination, nutrient cycling and water purification are essential services that are being provided by the ecosystem. These services are really very vital, important and useful for the sustenance of life, both for humans, plants and animals because they enhance social welfare.

In this scenario, Haley knows that plants and animals are made up of many different materials. She wants to know how these materials can cycle through an ecosystem. Therefore, the question Haley could ask to learn more about this topic is; what happens to the materials that make up a living organism after it dies?

Basically, the material that make up a living organism decomposes after it dies and are then used up as nutrients by plants growing on the soil.
