Given what we know, we can confirm that Salt marshes are an example of an ecosystem service. 
<h3>What is an ecosystem service?</h3>
This describes situations in ecosystems that are beneficial to human life. This example describes the way in which salt marshes provide humans with a steady and stable source of fish that are important to the fishing industry. 
Therefore, we can confirm that the Salt marshes are an example of an ecosystem service.

I think the independent variable is the temperature, while the dependent variable is the size of the balloon. The factor that is held constant is the amount of air in the balloon. An identical balloon kept at the original temperature. Independent variable in an experiment is the variable that the experiment plans to change while the dependent variable is the variable whose value depends on the independent variable. 
        
             
        
        
        
The physiological process occurring in the muscle cells that account for the gradual onset of muscle fatigue is called anaerobic the body is breaking down oxygen after than it can get in.
