The benefits are Beaches are better protected against erosion.
Trenches created in the ocean encourage species growth. 
WhatWhat are the advantages and disadvantages of beach nutrition?
Since nutrition just reduces the consequences of erosion and does not address its origins, it is usually a recurrent procedure. An agreeable setting lengthens the time between nutrient projects, cutting costs. On the other hand, a high rate of erosion might make nutrition unprofitable.
Sea turtles and rare and endangered birds alike depend on healthy beach and dunes systems. Important wildlife habitat areas that are endangered by erosion are provided by maintaining nourished beaches.

The above statement is true.
The operation of nuclear power plants in the United States is closely monitored and regulated. The NRC or Nuclear regulatory commission is the body that is tasked to monitor and regulate the construction and operation of nuclear power plants. Nuclear power plants use the heat generated from nuclear fission in a contained environment to convert water to steam, which powers generate to produce electricity.

The given diagram is food chain. Food chain is a sequence of populations or organisms of an ecosystem through which the food and its contained energy passes with each member becoming the food of a later membre of the sequence. The number of trophic levels in a food chain is 3-6 and in each trophic level a lot of biomass is consumed in liberating energy. 
In the above food chain plants( producers) radiant light energy into chemical form. Rodents are primary consumer, owl is a secondary consumers or primary carnivores and wolf is a tertiary consumer or secondary carnivores.
 
        
                    
             
        
        
        
By using ratios. You get a punnet square and then get the ratio or even the percentage.
