The correct answer is B. Logistic growth reflects density-dependent effects of birth and death rates; exponential growth is independent of density.<\/strong><\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

Exponential and logistic growth are two models used to describe population growth, but they have key differences based on the factors that influence them.<\/p>\n\n\n\n

    \n
  1. Exponential Growth<\/strong>:<\/li>\n<\/ol>\n\n\n\n
      \n
    • Exponential growth occurs when a population grows at a constant rate, with each individual contributing to an increase in the population size. This type of growth is described by the formula: [ N(t) = N_0 \\times e^{rt} ] where:\n
        \n
      • (N(t)) is the population size at time (t),<\/li>\n\n\n\n
      • (N_0) is the initial population size,<\/li>\n\n\n\n
      • (r) is the growth rate,<\/li>\n\n\n\n
      • (e) is Euler’s number (approximately 2.718).<\/li>\n<\/ul>\n<\/li>\n\n\n\n
      • This model assumes no limitations<\/strong> on resources, meaning the birth and death rates remain constant regardless of the population density. In other words, exponential growth does not account for the carrying capacity of the environment. As a result, the population grows rapidly and continuously, without slowing down, leading to a J-shaped curve on a graph.<\/li>\n<\/ul>\n\n\n\n
          \n
        1. Logistic Growth<\/strong>:<\/li>\n<\/ol>\n\n\n\n
            \n
          • Logistic growth, on the other hand, accounts for density-dependent factors<\/strong> that regulate population size. As a population increases, resources such as food, space, and shelter become limited. These limitations cause the growth rate to decrease as the population approaches the carrying capacity<\/strong> (denoted (K)) of the environment. The logistic growth model is represented by the equation:
            [
            N(t) = \\frac{K}{1 + \\left(\\frac{K – N_0}{N_0}\\right) e^{-rt}}
            ]<\/li>\n\n\n\n
          • The growth rate in logistic growth slows down as the population size approaches the carrying capacity. This results in an S-shaped curve, where the population increases quickly at first, then slows down as it approaches (K), eventually leveling off.<\/li>\n<\/ul>\n\n\n\n

            Key Difference:<\/h3>\n\n\n\n
              \n
            • Exponential growth<\/strong> assumes that resources are unlimited and does not take density into account, meaning it is independent of density<\/strong>.<\/li>\n\n\n\n
            • Logistic growth<\/strong>, in contrast, reflects the density-dependent<\/strong> effects of resource limitations, leading to a growth pattern that eventually stabilizes at the carrying capacity of the environment.<\/li>\n<\/ul>\n\n\n\n

              This is why B<\/strong> is the correct answer: logistic growth is influenced by density-dependent factors<\/strong>, while exponential growth<\/strong> is not.<\/p>\n","protected":false},"excerpt":{"rendered":"
