Sophia is studying the number of trees in a forest per square kilometer. What is the term used to describe this measurement?

• Carrying capacity

• Population density

• Limiting factor

• Exponential growth

In a newly discovered island, a population of rabbits is introduced with unlimited food and no predators. Which type of population growth is characterized by a continuous increase in the growth rate due to these unlimited resources?

• Logistic growth

• Exponential growth

• Carrying capacity

• Limiting factor

Rohan is studying a local pond ecosystem and wants to know the term that describes the maximum number of fish the pond can support. What is this term?

• Population density

• Exponential growth

• Carrying capacity

• Logistic growth

In a forest ecosystem, Aria is studying the deer population. She notices that the population size is not increasing as expected. Which of the following is a feature of the ecosystem that might be restricting the deer population’s size?

• Exponential growth

• Logistic growth

• Limiting factor

• Carrying capacity

Sophia is studying the growth of a rabbit population in a forest. She notices that when resources like food and space are abundant, the population grows rapidly. However, as resources become limited, the growth rate slows down. Explain how logistic growth differs from exponential growth in terms of resource availability.

• Logistic growth occurs with unlimited resources, while exponential growth occurs with limited resources.

• Logistic growth is limited by resource availability, while exponential growth is not.

• Both logistic and exponential growth are not affected by resource availability.

• Logistic growth is not affected by resource availability, while exponential growth is.

In a small town, the rabbit population initially grows exponentially. What might cause it to transition to logistic growth?

• An increase in resource availability

• A decrease in population density

• The introduction of a limiting factor

• A decrease in carrying capacity

In a forest, if the deer population reaches its carrying capacity, what is likely to happen to its growth rate?

• The growth rate will increase indefinitely.

• The growth rate will stabilize.

• The growth rate will decrease to zero.

• The growth rate will become negative.

Emma is studying a population of rabbits in a forest that is growing logistically. If the carrying capacity is 500 rabbits, what might happen if a disease reduces the carrying capacity to 300 rabbits?

• The rabbit population will increase to 500.

• The rabbit population will stabilize at 300.

• The rabbit population will decrease to 300.

• The rabbit population will continue to grow exponentially.

Benjamin is studying a fish population in a lake that is currently at its carrying capacity. What strategies could he implement to increase the carrying capacity of the lake?

• Introduce more predators to the lake.

• Increase the availability of food resources.

• Reduce the water quality of the lake.

• Decrease the size of the lake.
