Five Hypotheses Explain How Species Richness Affects Community Services

I-Elton’s hypothesis

II-rivet hypothesis

III-Redundancy hypothesis

IV-Keystone hypothesis

V-Idiosyncratic hypothesis

a) Species that play the same roles in a community can compensate for each other if some are lost under particular conditions

b) Community services change as the number of species increases or decreases

c) there is a linear correlation between species richness and community services

d) species is an organism that helps hold the system together

e)Some species play a small but critical role in keeping the plane
