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).
 
        
             
        
        
        
Answer:
Crustaceans and Molluscs play an important role in the oceanic carbon sink. 
Explanation:
Carbon sinks can serve to partially offset greenhouse gas emissions. Forests and oceans are both large carbon sinks. Algae is pressurized to bottom of the ocean by long term sequestration. Algae then falls to the bottom of the ocean and TRANSFORMS to fossil fuels. 
- CO2 is not combustible. 
- creates carbonic acid in the oceans. 
- Reduces seawater pH, carbonate ion concentration, and thus calcium carbonate (needed for shells for marine creatures, contributes to BOTTOM-UP EFFECT)
