Gobies are a type of small fish that live in small burrows.  Sometimes these burrows are created and maintained by burrowing shrimp.  The goby shares the burrow with the shrimp and uses it to protect its eggs.  The shrimp has poor eyesight, but monitors the behavior of the goby with its antennae.  When it feels the shrimp retreat into the burrow away from danger it quickly follows.  This relationship demonstrates which of the following? 

•  parasitism  
• mutualism 
• commensalism 
• predation

In an ecosystem, members of the lizards are observed eating members of the insect population.  In this same ecosystem, birds are also observed using insects as a food source.  The relationship between lizards and birds would best be described as –

• predator
•  competitive
• parasitic
• mutualistic
