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).
 
        
             
        
        
        
 The Outline  of the top-down effects on bacteria in the four mesocosms is 
- Zooplankton is bacterivores that help keep bacteria populations in Check.
-  Ingestion of zooplankton by fish leads to a rise in bacteria levels. 
<h3>What are 
mesocosms?</h3>
Generally, mesocosms are defined as any outdoor experimental system that investigates the natural environment in a controlled setting and may be thought of as a mesocosm.
In conclusion, Overview of top-down influences on bacterial growth in four mesocosms
To put it another way, zooplankton is bacterivores that play a role in maintaining a healthy bacterial balance.
Fish-eating zooplankton may cause an increase in bacteria in the water.

A numerical expression includes numbers and operations, so if youre wanting a numerical expression for the number 20, all you have to do is add, subtract, multiply, or divide numbers to equal that.
For example, 5+15=20, 4*5=20, 80/4=20, 29-9=20
