Remora are small fish with a sucker-like organ that allows them to attach themselves to larger animals like a shark. By doing this, the remora is able to gain protection from the presence of the shark while helping the shark stay clear from parasites. This relationship shows? Options: parasitism, mutualism, commensalism, predation

mutualism

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?  Options:  parasitism  , mutualism , commensalism , predation

The introduction of a non-native species into an ecosystem can result in serious ecological problems. This is often because the non-native species -

What factor would cause animals of the same species to begin competing with one another? Options: increase in precipitation, the presence of decomposers, the introduction of a new food source, limited supply of resources

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
