Ecological Communities: Networks of Interacting Species We wish to light upon: * What is an ecologic community and what kinds of interactions institute birth place indoors it? * How important ar the variant categories of species interactions, including mutualisms, commensalisms, disceptation and predation? * What kinds of interactions among species bring forth important when umteen an(prenominal) species tinge unitary another? * What consequences do these interactions feel for biodiversity  | Format for picture|   Species Interactions, nutriment Webs, and Ecological Communities An ecological community is defined as a group of really or potentially interacting species liveliness in the same place. A community is bound unneurotic by the network of influences that species have on sensation another. natural in this view is the look that whatever affects i species to a fault affects many others -- the balance of disposition. We build an understanding of communities by examining the two-way, and therefore the multi-way, interactions involving pairs of species or many species.
