    Which graph shows logistic population growth?

    Correct Answer
    A.
  • 3. 

    A species of plant has exponential growth after it is introduced into an area where it has never been. Which statement best describes exponential growth?

    • Each individual plant grows much larger than usual.

    • The population immediately decreases.

    • Within a few years the population increases dramatically.

    • The species cannot reproduce as well in a new habitat.

    Correct Answer
    A. Within a few years the population increases dramatically.
    Explanation
    Exponential growth refers to a rapid and continuous increase in population size over time. In the context of the given question, the introduction of a species of plant into a new area where it has never been before would lead to exponential growth. This means that within a few years, the population of the plant species would increase dramatically, as it adapts to and thrives in the new habitat.

    When is the population of rabbits growing exponentially? - ProProfs

    When is the population of rabbits growing exponentially?

    • May - Sept

    • April - October

    • August - Sept

    • June - July

    Correct Answer
    A. June - July
    Explanation
    The population of rabbits is growing exponentially in June - July because this is the breeding season for rabbits. During this time, rabbits reproduce at a rapid rate, resulting in a significant increase in their population.

    Rate this question:

  • 5. 

    Which of the following is not an example of exponential growth?

    • Deer on the Probilof Islands after eating most of the grass in the area

    • Mold appearing on bread overnight

    • Rabbit populations after being introduced to a new habitat with lots of food and space

    • A tree population, after seeds are planted in an area with unlimited sunlight, water, and minerals

    Correct Answer
    A. Deer on the Probilof Islands after eating most of the grass in the area
    Explanation
    The exponential growth is characterized by a rapid and continuous increase in population size over time. In the given options, all except "Deer on the Probilof Islands after eating most of the grass in the area" demonstrate conditions that are favorable for population growth. The deer population on the Probilof Islands would not exhibit exponential growth because their food source, grass, has been depleted, which would limit their ability to reproduce and increase in numbers.
