In a food chain we arrange the energy in the form of a pyramid. 
The producers are on the base of pyramid and then consumers are towards peak.
in the given food chain grass is being eaten by grasshopper which are food of birds.
Grasshoppers are also eaten up by Hawks. so both brids and hawks are feeding upon grasshoppers thus the amount of energy transferred from the grass to the grasshopper is the same as the amount of energy transferred from the grasshopper to the bird.

Answer:
157.79 g
Explanation:
The definition of molality is:
- molality = moles of solute / kilogram of solvent
This means that in a 2.7 molal solution, there are 2.7 moles of NaCl per kilogram of water.
So now w<u>e convert those 2.7 moles of NaCl to grams</u>, using its <em>molar mass</em>:
- 2.7 mol * 58.44 g/mol = 157.79 g
 
        
             
        
        
        
Just search it up on the internet:)
        
             
        
        
        
The density of an  object ρ = 24 g/ml
<h3>Further explanation</h3>
Given
mass of an object = 120 g
volume = 5 ml
Required
The density
Solution
Density is a quantity derived from the mass and volume  
Density is the ratio of mass per unit volume  
Density formula:  

ρ = density  
m = mass  
v = volume  
Input the value :
ρ = 120 g : 5 ml
ρ = 24 g/ml
