Explanation:
Protozoans are not the organism that fix nitrogen for the plants. The organism that fix nitrogen to convert it into a form which can be used by plants are known as diazotrophs.
These are bacteria and archae that fix nitrogen gas found in the atmosphere into more usable form such as ammonia.
These organism can grow without any external source of fixed nitrogen. Example: Rhizobia and azospirillium.

ATP is like a charged battery, while ADP is like a dead battery. ATP can be hydrolyzed to ADP and Pi by the addition of water, releasing energy. ADP can be "recharged" to form ATP by the addition of energy, combining with Pi in a process that releases a molecule of water.
        
             
        
        
        
Answer:
The root and shoot systems facilitate the ability to absorb, CO2, light, water, and minerals. The root system consists of the roots, and the shoot system consists of the stems and leaves. Angiosperms and vascular plants rely on these two systems. Roots are nonphotosynthetic and starve unless photosynthesates are absorbed through the shoot system. The shoot system depends on the roots to absorb nutrients.
