Answer:
phytoplankton
Explanation:
Phytoplankton can be defined as a set of photosynthesizing microorganisms that live floating on the water surface. It is composed of microscopic algae and cyanobacteria, which can be unicellular, colonial or filamentous. These microorganisms are defined as the primary producers of an ocean grazing food network.
Because phytoplankton live in aquatic environments - both in limic (eg lakes) and marine environments - they have a number of adaptations that guarantee their survival in the water column.  Some of these microorganisms, for example, have flagella that aid locomotion; others, in turn, have gas vacuoles that aid in flotation, while some of them have mucilage, which surrounds the cells and ensures protection, flotation and locomotion.
 
        
             
        
        
        
Answer:
The average energy of motion of particles in a substance is its kinetic energy. Therefore, temperature is the measure of the average kinetic energy of the particles of a substance. The thermal energy of the substance is the total energy of the substance.
