1. Pitcher Plants are homes to many organisms such as spiders, insects, and larvae. For example the spider gets food from insects that find their way into the pitcher plant, and the plant gets protection (some live insects are too big and dangerous for the plant to digest alone) as well as the food scraps of the spider. (Mutualism) "At least nine species of moths, mites and beetles live on sloths, eating the algae on their fur. The arthropods lay their eggs on the dung of the sloths, which provides food for the growing larvae. This relationship does not hurt of the sloth, but provides no benefit either." (Commensalism)
2. For commensalim. An example is bromeliad (plants living on trees in rainforests) and frogs; the frogs get shelter and water from the bromeliad but the bromeliad is unaffected. Mutualism. Leaf cutter ants live underground in the rainforest and have a mutualistic relationship with a fungus there. The ants cut the chunkc of leaves from trees even though they cannot actually digest the plant matter. They bring this plant matter back to the nest and cultivate a fungus. The fungus is fed by the plant matter from the ants, and in turn it provides food for the ants. Mutualism is any relationship between two species of organisms that benefits both species. Commensalim- One species benifits and the other doesn't get effected.
