When natural resources are unlimited, the populations grow very rapidly; this accelerating pattern of increasing population size is called:

The correct answer is Exponential Growth.

Key Points

• Exponential growth refers to the rapid increase in population size when resources are unlimited, resulting in a J-shaped growth curve.
• This type of growth occurs when the birth rate significantly exceeds the death rate, leading to accelerated population expansion.
• Exponential growth is often observed in ideal conditions where there are no limiting factors such as food, space, or predation.
• It is mathematically modeled as $P(t) = P_0 e^{rt}$ , where $P(t)$ is the population at time $t$ , $P_0$ is the initial population, $r$ is the growth rate, and $e$ is Euler's number.
• While exponential growth can occur temporarily, it is unsustainable in the long term due to environmental limitations and competition.

Additional Information

• Logistic Growth:
  • Logistic growth occurs when population growth slows down and stabilizes as it approaches the carrying capacity.
  • It is represented by an S-shaped curve and accounts for limiting factors like resources and space.
• Carrying Capacity:
  • Carrying capacity is the maximum population size that an environment can sustain indefinitely without degradation.
  • It is determined by the availability of resources, competition, and environmental conditions.
• Population Explosion:
  • Refers to an extremely rapid increase in population size, typically due to high birth rates and reduced mortality rates.
  • Population explosion can lead to resource depletion and environmental challenges.
• Factors Influencing Population Growth:
  • Birth rate, death rate, immigration, and emigration are key factors impacting population growth.
  • Environmental conditions, healthcare advancements, and socio-economic factors also play significant roles.
