Ecosystem is a community or group of living organisms that live in and interact with each other in a specific environment.
An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. These biotic and abiotic components are linked together through nutrient cycles and energy flows.
Answer:
A. If the aerobic pathway—cellular respiration—cannot meet the energy demand, then the anaerobic pathway—lactic acid fermentation—starts up, resulting in lactic acid buildup and "oxygen debt."
D. The rate of energy demand determines how the muscles will obtain energy, either from cellular respiration or from lactic acid fermentation if not enough oxygen is present.
Explanation:
It is important to consider that Kenny hikes all day but at a steady pace, whereas Janelle runs very fast. So Kenny's case, the supply of oxygen is sufficient to maintain aerobic respiration within the muscle cells. During this process only CO2, Water, and ATP are produced; therefore, there is no oxygen debt. We should keep in mind that the body shifts to anaerobic metabolism only when the supply of oxygen is limited.
In Janelle's case, running fast would need energy at higher rates and the supply of oxygen would not be sufficient to generate a high amount of ATPs. Therefore, to compensate for this deficiency, cells will start fermenting glucose to lactic acid and produce ATP and maintain energy demands. This lactic acid causes fatigue and this is why Janelle has aching and breathing hard. Breathing hard is also automatic reflux to inhale more oxygen and meet oxygen demands but even breathing hard would not be able to make it and the body will shift to anaerobic respiration automatically.

<h3>What is the main cause of pancreatitis?</h3>
Pancreatitis symptoms include the redness and inflammation of the pancreas. It could be chronic or acutely sudden (chronic). The two most frequent reasons are drinking alcohol and solid masses in the gallbladder (which can vary over time). The main objectives of treatment are to rest the pancreas and let it heal.
<h3>What treatment for pancreatitis works the quickest?</h3>
Mild acute pancreatitis will develop in a few days with rest and medicine. When your pancreatitis is more severe, you might also try the following additional treatments: Surgery. Your doctor can suggest cholecystectomy procedures to remove the gallbladder if stones are the source of your pancreatitis.
