Answer:
Hydrolysis.
Explanation:
Maltose is produced by hydrolysis of starch, in the presence of amylase, can be detected by colorimetric assay. As per the assay of hydrolysis of starch we have concluded from the test of enzyme activity of amylase is that maltose being a reducing sugar which reacts and reduces the DNS (3,5-dinitrosalicylic acid) that is basically a pale yellow colored alkaline which results after some minutes into 3-amino,5-nitrosalicyclic acid which orange red colored alkaline after heating.

<u>Answer:</u>
The fluctuations that are present  in abiotic cycles have an impact on living organisms and on ecosystems as a whole because any system that is present in a community requires the support of abiotic system 
The materials that are present in an environment require the involvement of both biotic and abiotic system. The biotic community comprises of the living organisms that coexists in an ecosystem whereas abiotic factors are the non-living factors that influences the living of organisms in an ecosystem.
 
        
                    
             
        
        
        
Organisms that live in water are not totally independent of soil as a resource. These organisms depend on aquatic plants for food and other substances. These aquatic plants in turn require minerals for their sustenance. These minerals are carried to waterbodies from soil by rivers, rainwater etc.
