Which of the 2 curves exhibits exponential growth?
Yellow J shaped curve
Green S shaped curve
Which of the 2 curves show carrying capacity?
Yellow J shaped curve
Green S shaped curve
What is the carrying capacity?
100
1000
900
It does not show carrying capacity
Give one hypothesis to explain why the population exceeded its carrying capacity in 1992.
If there were more predators, then the deer population would change.
If there was less rainfall, then the deer population would change.
If there were more food, then the deer population would change.
If there were a fire, then the deer population would change.
Isle Royale National Park on a remote island was established in 1940, and designated a wilderness area in 1976. The only mode of transportation available is by boat or seaplane. Moose first arrived at Isle Royale around 1900. The moose population tends to increase in years with mild winters, early spring green-up, abundant winter forage, low wolf numbers and low levels of tick infestation. Wolves first arrived at the island on an ice bridge from Canada in 1940. Disease has also influenced the wolf population. Between 1980 and 1982, the wolf population declined from 50 to 14, due to canine parvovirus.
What is the greatest moose population?
3000
2500
2000
1500
