Adhesion is the force of attraction between two dissimilar molecules or substances, and Cohesion is the force of attraction between two similar substances or molecules. An example for adhesion is the force of attraction lying between the walls of xylem vessels and the water molecules, and an <span>example for the cohesion forces is the force of attraction between the water molecules.</span>
        
             
        
        
        
Kinda like a pyramid. The bottom is wide, many sources of energy (plant life) that take nutrients combine them with water use the bonding of the suns rays and convert that to matter. This matter is then consumed by animals (grazers and browsers), who in turn are fed upon by predators. With man as the top predator. 
Take a few seeds from wire-grass. Wire-grass grows in many natural communities, it is eaten by rodents and birds, like Quail. Quail are eaten by snakes, who are eaten by hawks, bobcats, and raccoons. 
every time the meal is transferred from one critter to the next, energy is expended in the chase (heat) and capture, and energy is always being used for the animals to survive day by day.
        
                    
             
        
        
        
<h3><u>Answer;</u></h3>
Both use energy sources to create ATP
<h3><u>Explanation;</u></h3>
- Autotrophs and heterotrophs must use energy in the form of ATP to synthesize organic compounds. 
- Autotrophs and heterotrophs are both living organisms that require some form of food to get energy. 
- However, autotrophs make their own food via photosynthesis or some other similar method. Heterotrophs get their food by eating autotrophs or other heterotrophs.
 
        
        
        
Correct answer is A hope this helps
        
             
        
        
        
Sunlight doesn't reach quite as well in deeper parts of the ocean. Therefore, the autotrophs cannot use photosynthesis to make food.
