How can you explain the increased sensation of palpitations and increased heart rate in this patient with hyperthyrodism?

Density-dependent factors include disease, competition, and predation. Density-dependant factors can have either a positive or a negative correlation to population size. With a positive relationship, these limiting factors increase with the size of the population and limit growth as population size increases.

Explanation:

In a population at its carrying capacity, there are as many organisms of that species as the habitat can support. If resources are being used faster than they are being replenished, then the species has exceeded its carrying capacity. If this occurs, the population will then decrease in size.
