Transcript text: What happens when environmental resistance (factors that oppose growth) becomes greater than biotic potential (factors that cause growth)?
Solution
The answer is the first one: population decline.
Explanation for each option:
Population decline: This is the correct answer. When environmental resistance becomes greater than biotic potential, the factors that oppose growth (such as limited resources, predation, disease, and competition) outweigh the factors that promote growth (such as reproduction and survival rates). As a result, the population is unable to sustain its numbers and begins to decline.
Population growth: This is incorrect. Population growth occurs when biotic potential exceeds environmental resistance, meaning the conditions are favorable for the population to increase. In this scenario, the opposite is true, leading to a decline rather than growth.
Population fluctuation: This is incorrect in the context of the question. Population fluctuation refers to variations in population size over time, which can occur due to various factors. However, when environmental resistance consistently exceeds biotic potential, the trend is towards decline rather than fluctuation.
In summary, when environmental resistance is greater than biotic potential, the population is likely to decline.
