Why has the population been able to grow so quickly in such a short period of time?

• Doctors have developed easier and safer ways to have babies
• People needed more help to work their farms so they had more children
• Because people stayed in one place and only moved when crowded out
• Because of medical care, clean water and better access to nutritious food

Will competition increase/decrease the carrying capacity of an ecosystem for the animal in competition?

• Decrease
• Increase

Cattle egrets forage (feed) in fields among cattle. The egret gets easy access to flying insects stirred up by the cattle, and the cattle don't care if they are there or not.

• commensalism
• competition
• parasitism
