Answer:
They provide nutrients for the growth of plants  
Explanation:
When plants and animals die, they become food for decomposers like bacteria, fungi and earthworms. Decomposers or saprotrophs recycle dead plants and animals into chemical nutrients like carbon and nitrogen that are released back into the soil, air and water.

Answer:
The sine or sin is a trigonometric function of an angle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle, to the length of the longest side of the triangle (the hypotenuse).

Explanation:
 
        
             
        
        
        
the specific gravity of
pure sulfuric acid is---------> approximately 1.835 g / cm3 
the specific gravity of
water is -------------------- >1.000 g / cm3.
 The electrolyte, that
is, the dissolution of sulfuric acid in water, is usually at a rate of 36%
acid, so that, in a fully charged element, we can deduce the electrolyte
density, is 1.295 g / cm3. (see attached table)
The specific gravity is
actually the difference in the weight of water compared to a specific fluid. It
is measured with a hydrometer
