Which of these describes a mutually beneficial relationship between two organisms?

• A dog with worms in its intestine
• A turtle and a snail that both eat grass live in a river
• A honeybee pollinating a plant and receiving nectar for food
• A small fish attached to a shark, eating tiny pieces of the shark's food as it floats

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.

• mutualism
• commensalism
• competition
• parasitism

Red-billed oxpeckers are birds that often feed on parasites that infest impala.  This is an example of _______.

• commensalism
• mutualism
• neutralism
• competition

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

• Density Independent limiting factors start to occur resulting in the population going farther above carrying capacity.
• Density Dependent limiting factors start to occur resulting in the population going back below carrying capacity.
• The population will go extinct due to lack of resources
• The population grows then finds a new carrying capacity
