Which scenario is an example of uninhibited growth?

Uninhibited growth refers to the expansion of a population or organism without significant constraints from environmental factors, resources, or competition. In the scenario where a species is introduced to a new ecosystem, it often experiences rapid growth because it may face fewer predators, less competition for resources, or abundant resources in that new environment. This ideal situation allows for exponential growth as the species adapts and proliferates without the limiting factors prevalent in its original habitat.

In contrast, the other scenarios illustrate varying forms of growth regulation. For instance, population growth in a crowded city is generally limited by space, resources, and competition among inhabitants. Similarly, a plant growing in a controlled environment is fostered through regulated conditions that may not allow for uninhibited expansion once it reaches capacity. The growth of bacteria in a lab with limited resources also exemplifies constrained growth, as the bacteria will encounter limitations once the nutrients are depleted or waste products accumulate. Hence, the scenario that best exemplifies uninhibited growth is the introduction of a species into a new ecosystem.
