What is the carrying capacity for this sheep population?

• 1.8 million
• 1.25 million
• 1.6 million
• 1.o million

When a population grows past the ecosystem's carrying capacity, what happens to the population?

• Continues to grow
• The population starts to die off to return to carrying capcity
• The population will go extinct due to lack of resources
• The population grows then finds a new carrying capacity
