Detailed explanation-1: -As population size approaches the carrying capacity of the environment, the intensity of density-dependent factors increases. For example, competition for resources, predation, and rates of infection increase with population density and can eventually limit population size.
Detailed explanation-2: -As a population approaches its carrying capacity, the growth rate slows because of limiting resources. Logistic Growth is density-dependent which means that the growth rate depends on the population density.
Detailed explanation-3: -Answer and Explanation: The correct answer is (B) If a population is at the carrying capacity of the environment, then the birth rate will more or less equal the death rate (i.e., zero population growth).
Detailed explanation-4: -So, the correct answer is ‘limiting resources’
Detailed explanation-5: -In logistic growth, a population’s per capita growth rate gets smaller and smaller as population size approaches a maximum imposed by limited resources in the environment, known as the carrying capacity ( K). Exponential growth produces a J-shaped curve, while logistic growth produces an S-shaped curve.
