Cortisol hormones are stress hormones that increase blood glucose levels. When the level of happiness increases the level of cortisol does not increase.
<h3>What are cortisol and its function?</h3>
Cortisol is the steroidal hormone that is produced in the cortex of the adrenal glands and is discharged in the blood vessels when in stress or danger.
It has a variety of functions including regulation of the blood pressure, response to the stressful condition and increase of the metabolism of the body.
It also acts as happiness hormones along with adrenaline and oxytocin but is a major flight or fight hormone and increases the heart rate in dangerous conditions.

The principle of competitive exclusion states that two species cannot occupy the same niche.
<h3>
What is competitive exclusion?</h3>
- Two species cannot coexist in the same ecological niche for very long without one becoming extinct or being driven out because of competition for limited resources.
- In Britain, the red squirrels have displaced the grey squirrels as an example of competitive exclusion.
- Due to diseases, competitive exclusion, and the elimination of hazelnuts, there were fewer red squirrels.
- Red squirrels were eventually displaced by gray squirrels, who quickly adjusted to their surroundings.
- Two species with identical niches cannot survive indefinitely, according to the "competitive exclusion principle" (CEP).
- According to the competitive exclusion principle, only one conclusion is feasible when two competing life forms try to inhabit the same niche: One of them will extirpate the other.
