How did Charles Darwin use the concept of density dependent factors in his Theory of Evolution
OLEGan [10]

Answer:

Density-dependent factors are defined as the biological factors which are utilized by the population as a resource for example- food and shelter. Charles Darwin uses the concept of density-dependent factors in his Theory of Evolution to show how it affects population growth and mortality.

Charles Darwin used factors like competition, predation, and parasitism in his Theory of Evolution. He explained that habitats are limited by space and resource availability, and only the fittest organism will survive the competition.

Predator-prey relationships create density-dependent limiting factors and balance the ecosystem with limited organisms. If predators will increase in an ecosystem it will decrease the population of prey and after a certain time there will be a shortage of food as they are limited resources.
