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

• Continues to grow

• The environment degrades causing the population to crash

• The population will increase the carrying capacity of the ecosystem

• The population is not affected by the carrying capacity and does whatever it wants to

When organisms move out of the population, this is known as

• emigration

• natality

• immigration

• mortality

which statement sounds accurate based on the graph data. 

• The zebra and lions do not affect each other
• when lions population increases, so does the zebra population
• When the zebra population increases, it causes the lion population to also increase
• when zebra populations go down, the zebra population goes up.
