Competition because they are fighting over a limited resource.
Answer:
Cellular respiration
Explanation:
Respiration is the process by which energy is made. Aerobic respiration requires oxygen.
All the other processes listed do not require oxygen to.
The answer is Glycogenolysis
When we are hungry or skipped a meal our glucagon, <span>an hormones</span> that regulates blood-sugar levels, is released to avoid glucose levels in the blood to decrease to a risky value.
Glucagon makes the liver, but also the muscle, to breakdown accumulated glucose called glycogen into glucose to increase blood-sugar levels. This process is called Glycogenolysis and can also be stimulated by an increase in epinephrine during fight-or-flight responses.
Controlled burning? I think that's right.
