Energy flows from one animal or plant eating or getting eaten to the next anima above it. As for your translation, the crickets are eating the grass then are getting eaten by the secondary consumers and finally getting fed to the largest consumer and every time you go up in the food chain more and more energy is being passed on.
        
             
        
        
        
Type of symmetry in which body parts are arranged in a circle around a central point is called radial symmetry.   
<span>
This type of symmetry is characteristic for the sessile animals like Cnidaria and Echinodermata. Organisms with radial symmetry have no left or right sides, they have a top and a bottom surface, or a front and a back.</span>

Answer;
Phospholipid.
Phospholipid forms a double layer as the primary structure of cell membranes.
Explanation; 
Cell membranes contains of lipids (phospholipids and cholesterol), proteins and carbohydrates groups that are attached to some of the lipids and proteins. 
Phospholipids are composed of a polar head and non-polar (hydrophobic) tail. They line up such that the heads and the tail groups are side by side to form a single layer due to the interactions between the head groups and the tail groups. Two of these layers line up with the hydrophobic tail groups facing each other to prevent the hydrophobic groups away from the polar head groups of other phospholipids and from the water in the surrounding environment.
