Answer:
A
Explanation:
The dead matter from organisms such as plants and animals that die need to be recycled so the nutrients in the matter are released and used up by other organisms. This is how sustainability is achieved in ecosystems through a cyclical nature of nutrients flow. Decomposition of the dead matter is done by decomposers such as fungi and bacteria. Without them, the dead matter would accumulate while the soil would lack nutrients for plants to grow and for other bacteria to utilize for energy. This would affect the rest of the food chain/web causing the ecosystem to collapse.
Well, the food is in the environment. I would like to compare it with how bacteriae feed (however my biology is quite rusty), that is, they engulf their food and they "digest" -- not the proper term, since there are no organs to do real digestion -- it.

I believe the answer is Axis III
In psychiatric problem, the doctor could make diagnosis in 5 different axis to make sure they assess the patient comprehensively. Axis III is dedicated for general medical condition. In this case, serious cystic acne and bad skin would be categorized as general medical condition because it was not psychological or personality disorder.
