This predator-prey graph tracks the wolf and moose populations in a certain ecosystem over the past hundred years. What is most
PSYCHO15rus [73]

Answer:

1,400

Explanation:

The carrying capacity is the maximum population size of the species that the environment can sustain indefinitely. When the population reaches its carrying capacity, it begins to decrease due to shortages of resources, such as food, water, habitat, and other necessities.

In the given example, we can see the moose population begins to grow when it reaches about 800 individuals. Then, the population keeps growing until it reaches above 1,400 individuals, after which it begins to decrease. Based on that, we can conclude that the carrying capacity of moose in this ecosystem is 1,400.
