A) Availability of vegetation for moose
B) Birth rate of wolves
C) Prey availability, particularly moose
D) Reproductive rate of wolves

**Question 2:**
How do the populations of moose and wolves on Isle Royale interact to maintain ecosystem balance?

A) Wolves directly influence the food supply for moose.
B) Moose and wolves are independent and do not affect each other.
C) Wolves regulate the population of moose by predation, which in turn affects wolf survival.
D) Wolves and moose both rely on the same predators, which regulates their populations.

**Question 3:**
Which of the following interactions could result in a stable ecosystem in the Isle Royale food web?

A) An increase in the wolf population causing the moose population to dramatically decline.
B) Moose populations are stable, leading to a steady food supply for wolves.
C) A decrease in food availability for both moose and wolves, leading to increased competition.
D) The introduction of a new predator to the ecosystem, significantly affecting the moose population.

Answer :

Final answer:

The populations of moose and wolves on Isle Royale interact through predation, where wolves regulate moose numbers. This relationship is cyclical, affecting both populations and maintaining ecosystem balance. External environmental factors also influence their interactions.


Explanation:

Interactions Between Moose and Wolves on Isle Royale


The populations of moose and wolves on Isle Royale illustrate a classic example of predator-prey dynamics, which are crucial for maintaining ecosystem balance. These interactions are reflected through several mechanisms:



  2. Wolves regulate the moose population through predation. As wolf numbers increase, they hunt more moose, which leads to a decrease in the moose population.

  4. This predation pressure affects the moose's birth and survival rates. With fewer moose available, wolves may experience food scarcity, which in turn can lead to a decline in wolf population.

  6. This cyclical relationship demonstrates that the populations of both species influence each other, creating a balance. When moose populations decline due to increased predation, this can lead to less competition among the remaining moose and eventually allow their numbers to rise again when wolf numbers drop.


Additionally, external factors such as vegetation availability and environmental conditions can impact these populations. The interactions on Isle Royale do not follow simple models but are complex and influenced by multiple factors.


Conclusion


Thus, the relationship between moose and wolves showcases the dynamic interactions necessary for a balanced ecosystem.
