Atlantic puffin

These puffins use burrows for nesting that were made by rabbits.

One organism benefits from the help of another, but the second organism is not harmed nor does it benefit

The rabbits make the burrows and the atlantic puffin kicks them out of their burrow to use for nesting

One benefits, the other does not benefit, but its not harmed

The rabbit is not harmed or does it benefit but the Atlantic puffin does benefit

Linx chasing Hare

the Canada lynx lies in wait for its favorite prey, the snowshoe hare. Positioning itself along one of the well-beaten trails connecting the hare’s feeding and nesting sites, the lynx sits patiently, its mottled gray coat camouflaging it in the brush. And whether for the thrill of the chase, the tantalizing taste of the hare, or a combination thereof, the lynx will wait hours on end for this moment, the opportunity to pounce on an unsuspecting snowshoe hare.

One predator captures, kills and consumes the prey

The Lynx captures, kills and consumes the hare

One benefits and one dies

The Lynx benefits and the hare dies

cheetahs and lions

since both species feed on similar prey, they are negatively impacted by the presence of the other because they will have less food, however they still persist together, despite the prediction that under competition one will displace the other.

Two or more species use the same limited resources

Both the cheetah and the lion feast on the same prey

One might benefit, but often neither does

Neither the cheetah or the lion benefit by competing for their food

The relationship between goby fish and shrimp.

The shrimp digs a burrow into the sand and both organisms live there. Because the shrimp is almost blind, the goby fish will touch the shrimp when a predator is near.

Organisms live together and benefit from the help of each other

The shrimp helps the goby fish by digging the burrow for both of them to live in, and the goby fish returns the help by touching the shrimp when it is in danger

Both Organisms benefit

Both the shrimp and the goby fish benefit

Aphids

Aphids eat sap from plants

Aphids are soft-bodied insects that use their piercing sucking mouth parts to feed on plant sap. They usually occur in colonies on the undersides of tender terminal growth. Heavily-infested leaves can wilt or turn yellow because of excessive sap removal.

A parasite organism feeds on and often even lives on a host organism

The aphids live and feast on the plants sap

One benefits and one is harmed

The aphids benefit by being able to get food and the plant is harmed by the sap being taken from it and not having enough nutrients to stay healthy
