This water has bacteria in it specifically archeabacteria.

This snake at the zoo is eating a dead rat. Which is commensalism.

 My pet fish are ectothermic orgamisms which means their body tempreture is as cool as the water they live in.

 This butterfly shows mutualsim because both the butterfly and flower benefite from this. The butterfly gets nutrients and the flower is pollenated.

These wild strawberries are showing a niche becuase the have their place in the enviroment and are fufilling that place.
