3.2 Logistic & Exponential Growth
-
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.
-
This quiz titled '3.2 Logistic & Exponential Growth' explores population dynamics, focusing on exponential and logistic growth patterns in species. It assesses understanding of growth trends, carrying capacities, and real-world examples, crucial for students of ecology and biology.

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 areaExplanation
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.Rate this question:

Which graph shows logistic population growth?
Correct Answer
A. -
- 4.
What is the approximate carrying capacity of this population?
-
55
-
65
-
20
-
5
Correct Answer
A. 65Explanation
The approximate carrying capacity of this population is 65. This means that the population can sustainably support around 65 individuals without depleting its resources or causing harm to the environment. This is the maximum number of individuals that the population can support in the long term.Rate this question:

When is the population of rabbits growing exponentially?
-
May - Sept
-
April - October
-
August - Sept
-
June - July
Correct Answer
A. June - JulyExplanation
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:
