Tissue damage activates nociceptors or pain receptors in the skin. A signal is sent to the peripheral nerve to the spinal cord where neurotransmitters or chemical messengers are released. It activates other nerves to pass signal to the brain. The signals are relayed to the somatosensory cortex for sensation, frontal cortex for thinking and limbic system for emotional response.

Answer:
The microorganism creates its own energy.
Explanation:
Based on the pattern of nutrition, a living organism can either be autotrophic or heterotrophic. Autotrophic organisms are those organisms capable of synthesizing its own food or energy source using light (photosynthesis) or chemicals (chemosynthesis). Heterotrophs, on the other hand, cannot synthesize their own food, hence, they depend on other organisms for energy.
According to this question, a researcher claims that a newly discovered microorganism is an autotroph. For this claim to be true, this means that the microorganism must be capable of CREATING ITS OWN FOOD/ENERGY either by photosynthesis (light) or chemosynthesis (inorganic chemicals).
From the following items:

4.fibers to make cloth
5. drugs such as aspirin
6. fossil fuels such as oil, gas, coal and nutrient-rich soil
ALL of these things are one way or another, exist because of green plans. E.g. Oxygen is released by plans, while wood for furniture comes from trees.
All fruits and vegetables are grown on plans while even meat comes from animals who eat green plans.
Fibres such as wool also come from animals which eat plans, and fossil fuel is made from the remains from millions of years of old plans in the ground.
